We live in four dimensions! Explained.

When you want to meet some one what would you do? You give the address where to meet but is it enough? The answer is no. You also have to give a time. So to give an address to someone is meaningless if you don't give a time to meet. So you have to give address in three dimension and an extra dimension of time so total becomes 4 dimensions.

We have been taking time dimension for granted and never mentioned it until Lagrange did 1788 in his his Mécanique analytique. Strange thing is we can all experience a three dimensions and luckily we can point them our but we are trapped in this three dimension such that we cannot point towards a fourth dimension and have no clue about it how to get there. 

Its like people living in flat land where everything is two dimensional including them self cannot imagine or point or travel to the fourth dimension but can deduce it by the strange appearance of the 3d object in 2d and because the existence of 2 dimension world cannot be explained. Can you image a paper lying somewhere without the third dimension. The answer is no.

Lets take a look in an elaborate way draw a line its one dimensional, duplicate the line and move perpendicular to the previous line and connect the vertices you get two dimensional figure now you pull the square out of the paper and make it solid now it became three dimensional and at last it is a little hard to explain to pull the three dimensional object in the fourth perpendicular to three dimensional figure then you will get a four dimensional figure. now I cannot explain where to point at the four dimension because the third is inside the fourth one so I have to show the outside which i clearly can't show.

Even after all this exdplaination if you still can't understand then it's not your fault, it is because we are trapped in 3d that we cannot even imagine 4d. But the fact is we do live in four dimensions. That is why we give time for meeting and not just address.

How much amount of uranium you need to eat to die?

Uranium is a naturally occurring element that makes up approximately 2–4 ppm of the earth=s crust. It is more plentiful than silver and about as abundant as molybdenum or arsenic. Uranium is an actinide element, and has the highest atomic mass of any naturally occurring element.

Uranium is a hard, dense, malleable, ductile, silver-white, radioactive metal. Uranium metal has very high density obviously. When finely divided, it can react with cold water. In air it is coated by uranium oxide, tarnishing rapidly. It is attacked by steam and acids. Uranium can form solids solutions and inter metallic compounds with many of the metals.

With the developments in nuclear energy Uranium gained importance. Depleted uranium is used as shelding to protect tanks, and also in bullets and missiles. The first atomic bomb used on Hiroshima was a uranium bomb. This bomb contained enough of the uramium-235 isotope to start an uncontrolled chain reaction which in a fraction of a second caused a large number of the uranium atoms to undergo fission, there by releasing a tremendous amount of energy instantly vaporising whatever was engulfed in the heat of the bomb at the centre of the explosion..

People always experience exposure to a certain amount of uranium from food, air, soil and water, as it is naturally present in all these components. So coming in contact is inevitable. Food, such as root vegetables, and water will provide us with small amounts of natural uranium and we will breathe in minimal concentrations of uranium with air. The concentrations of uranium is in fractions of microgram and more over the body is not made to absorb uranium so 90 % goes in faeces and 70 % goes with urine of what's remaining.

But if still you eat uranium about 50 milligram you will die of kidney failure and other renal damages before you die of radiation poisoning.

People that live near hazardous waste sites, people that live near mines, people that work in the phosphate industry, people that eat crops grown on contaminated soil or people that drink water from a uranium waste disposal point may experience a higher exposure than other people. 

Uranium is a radioactive substance health effects have been researched. Scientists have detected no harmful radiation effects of natural levels of uranium. However, chemical effects may occur after the uptake of large amounts of uranium and these can cause health effects such as kidney disease.

How to levitate for real?

Clarke's Three Laws are three "laws" of prediction formulated by the British science fiction writer Arthur C. Clarke. They are:

1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
3. Any sufficiently advanced technology is indistinguishable from magic.

Levitation has always been a magic trick which never fails to amaze the viewers. In this article we will take a look, what happens when science wants to make things levitate no tricks only magnetism.


The Iron and other ferromagnetic materials (that is, ones that are naturally drawn to a magnet) are themselves made up of lots of individual minute magnets.These tiny magnets all line up in parallel when put next to a magnet. This allows the iron or ferromagnetic substance to produce its own magnetic field and attract the permanent magnet. The condition for this to happen is that there must be substantial concentrated amount of iron to be in the vicinity of the magnet. 

Our blood contains only 5 grams of iron which is evenly distributed in 4.7-5 litres of blood in an average person so getting affected to a magnet just because of iron is doubtful.But it cannot be said that we are not affected by very strong magnetic fields. It is not because of iron in the body and it is certainly not attraction but instead magnets repel water and 60 % of our body is water this is because of phenomena of diamagnetic property of water. 

The magnetic strength is measured by an apparatus called magnetometer or also called gaussmeter. The magnetism is measured in Tesla which is a standard international unit. But do you know that how much is one Tesla lets take a look first we have to convert 1 Tesla into gauss which is a sububit like centimetres and metres. 

1 TESLA = 10,000 Gauss

Earth's Magnetic feild = Half gauss

Fridge magnet = 100 gauss

MRI = 1500 gauss

Now you can imagine that even the MRI which has a strong magnet is only has 0.015 Tesla strength. So one to levitate needs how many Tesla Magnetic strength depends on Size of the magnet, distance of the magnet and many more parameters. But a frog is a different question it can levitate at least it hovers if placed in a magnetic field of 16 Tesla. It has been already tested in Nijmegen High Field Magnet Laboratory.

So to levitate you don't need to be Magneto just buy a super-strong magnet obviously much higher that 16 Tesla and make sure you have the capacity to carry it around. See the Magic yourself in the below given video.

Beethoven's Warehouse and μTorrent, an analogy.

 (Listen to a Beethoven music of your choice while reading this)

  Ludwig van Beethoven (1770-1827) was a German composer and a pianist. He is a known crucial figure in the transition of classical to romantic era (from strict rhythm and church based to more emotional and mood elevating) in western art music. He is considered as one of the greatest European composers who ever lived.

He is quoted as saying:

"There ought to be but one large art warehouse in the world, to which the artist could carry his art-works, and from which he could carry away whatever he needed. As it is, one must be half a tradesman."

He talks about a single warehouse where artists from any part of the world can contribute and, at the same time, take back whatever they require. Most possibly, "half a tradesman" means that the transaction will be in a barter system basis.

Naturally, he was worried of fragmenting all musical scores, that ever existed, to private hands and losing them. There were no systematic collection and archival of musical scores in his times other than a few churches and libraries.

From my observations, it wasn't until 204 years later when Ludvig Stregeus (another Ludvig???)  had his first public release of μTorrent beta 1.1 in 2005 followed by its purchase by BitTorrent in 2006. It went on to become the second most popular BitTorrent client around the world.

Most of us know what a p2p file sharing system is where one person downloads and at the same time uploads the same file/portion of the file (seeding) in a preferable 1:1 ratio. Sounds familiar now? Yes! Half a tradesman basis, in a single warehouse (software), around the world! Do you think that the two Ludwigs same basic idea a mere coincidence? Well, I don't know!

Fast Forward, many Torrent sites have invited bad rap for encouraging piracy, including almost all of Beethoven's work. They are considered an invaluable treasure of western classical music. His 9th symphony was composed when he was completely deaf and it was selected as the anthem of European union.

Political egos aside, Beethoven never really wanted to monetise his music. He could have been a millionaire by today's standards if he ever wanted to, yet he preferred a life of solitude, living in lodges with his piano and along with love failure, alcoholism, drug abuse, diseases etc. 

"One clashes with stupidity of all kinds. And then how much money must be spent in advance! The way in which artists are treated is really scandalous. I am compelled to give a third of my receipts to the manager of the theatre and a fifth to the hospitals. Devil take them! As long as these abuses exist, I shall always ask whether music is or is not an art that may be freely exercised. Believe me, there is nothing to be done for artists in times like these." 

He considered music as divine and so his own. He wanted his music to be "seen" by everyone. That holds true for all real musicians and artists.

If Beethoven was alive today, he would have been really happy seeing his "warehouse" working in full steam and less bothered by the onslaught of piracy going on; or at least smiling in his grave

You're welcome!





 

Scent Marketing? It is not what you think!

You might have experienced that when you see a picture of a certain event brings back memory and make you remember the old days. Well that is the purpose of keeping pictures to remember the moments when we were happy. This is called an associative memory because we or lets say our brain associate certain visual stimulus to a certain set of memories. The process by which brain makes association of two stimuli or one behaviour and stimuli is called associative learning. 

We might all know how photographs and visual media works but just don't know the technicality behind it. But some times even marketer take advantage of this phenomena and associated their brand  with some kind of visual stimuli like a logo, colour, Trademark etc. 

But these are all about visual stimuli but does this happens with smell too? The answer is yes our brain can associate all senses like smell, sound, touch and taste. 

A smell can bring on a flood of memories, influence people's moods and even affect their work performance. Because the olfactory bulb is part of the brain's limbic system, an area so closely associated with memory and feeling it's sometimes called the "emotional brain," smell can call up memories and powerful responses almost instantaneously.

The olfactory bulb has intimate access to the amygdala, which processes emotion, and the hippocampus, which is responsible for associative learning. Despite the tight wiring, however, smells would not trigger memories if it weren't for conditioned responses. When you first smell a new scent, you link it to an event, a person, a thing or even a moment. Your brain forges a link between the smell and a memory -- associating the smell of chlorine with bleaching of water or incenses with a funeral ritual. When you encounter the smell again, the link is already there, ready to elicit a memory or a mood. Same smell can trigger different memories in different people because everyone makes different association of smells in brain. Earlier talked incense sticks bringing back memory of funeral but at the same time it may bring the memory of a temple for some people.

Scent marketing is the latest type of marketing to stand out from the visual and auditory stimulus that dominates advertising.  In this type of marketing the companies associate smell with their brand. Developers use carefully tuned scents to lure customers into a sense of well-being. Stores that sell shoes or shirts, items ideally not associated with odor, formulate aromas of ivy or crisp linen. Some companies even strive to develop a "brand scent," something that customers will associate with the company as much as a logo.

A salute to India's wings of fire. Dr. APJ Abdul Kalam.

11th  president of India and Bharat Ratna Dr.APJ Abdul Kalam passed away on Monday after collapsing during a lecture in IIM Shillong.

Kalam, 83, who reached Shillong via Guwahati morning 27th July 2015, collapsed during a lecture at the Indian Institute of Management-Shillong (IIM-S) around 6:30 pm IST. The cause of death was cardiac arrest.

 “The body of the former president will be flown to New Delhi via Guwahati Tuesday morning,” Warjri said.

IIM-S officials said Kalam, who had tweeted in the morning about the function, showed no signs of illness after he reached the Meghalaya capital. “We had a packed house for the lecture on Liveable Planet Earth,” an official said.

Dr A P J Abdul Kalam served as president for five years from 2002, enjoying the support of both the ruling BJP and the opposition Congress.

Kalam  was closely involved in the country's civilian space programme and military missile development efforts, earning him the sobriquet  'India's Missile Man'.  He worked as a scientist and science administrator, mainly at the Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO) before he became president.

He also played a pivotal technical and political role in India's Pokhran-II nuclear tests in 1998, shortly after the Atal Bihari Vajpayee government came to power.

After his term, he returned to a life of education, writing, and public service. He received several prestigious awards, including the Bharat Ratna, India's highest civilian honour.

The Centre has declared a national mourning of seven days.

"Dr. Kalam was a man of impeccable character, indomitable spirit, profound knowledge and firm conviction. His death is an irreparable loss to this nation. He has left a big void hard to fill," said home minister Rajnath Singh.

Avul Pakir Jainulabdeen Abdul Kalam was born on 15 October 1931 in a poor Tamil Muslim family in Rameswaram. But he overcame all odds to study physics and aerospace engineering and thus became legend in the hearts of everyone.

Even though he passed away bur will always be remembered for he was 'The legend'. The Wings of Fire will continue to burn in our hearts that was lit by this 'Missile Man of India'.

Why diets never work?

Having been a victim of "overweight induced disappointment", I was on months long weight-loss war on previous years which achieved a total loss of 20kg through following the advice of a Mayo website here. Their theory, based on a low-carb diet, surprised me since I thought fat consumption was a leading cause of weight gain.

One day I said go to hell and decided to drink a cup full of coconut oil to test on myself the effects oils make on human body. The act was torturing and I am not daring to details here. I felt a momentary burning sensation in the back of the throat and fullness of stomach the whole day! I even thought my end was near!. I was welcomed by a short bout of diarrhoea and soapy poop the next morning. I noticed to my surprise that my body was actually removing those excess fats  and that day I lost a marginal amount of weight! I actually began to feel really light and I could exercise and spend the day like normal.

My weight continued to spiral down for another few days despite going on a “dietless mode” likely due to various phenomena that're explained nicely here. I observed a few interesting things:

•  Logically it would take a person to ingest 1kg of oil to increase 1kg of weight, according to the law of conservation of mass (duh!) and practically it takes months for a person to achieve that.

• Human body never goes to hibernation mode; it is burning energy all the time, even during sleep. This means that if the above person did drink 1kg of fat, he won't gain as much for a long time.

• Our bodies are designed to stay active all the time. This makes us wonder whether our hunter-food-gatherer forefathers actually looked healthier before an agriculture-based sedentary civilisation kicked in.

• According to an article here, saturated fats never make any real difference in weight gain. This made me happy and used lots of ghee (yum!) on every food I consumed for a week, and the theory was true!

The whole “fat is bad for you” was actually based on an erroneous food pyramid that placed high carb foods in the “more to consume” section. So huge corporates got into their high horses and released tonnes sugary cereal and bread based packaged products which, not surprisingly, coincided with obesity hysteria of 1990s. Diary and meat farm owners were just unlucky to compete with them.

There was a time when all of us were happy with our figures. Everyone ate what they could afford and only thought about health once senility kicked in. Traditionally no cultures recognised the need of a “diet plan” unless and until old age related diseases showed up. This, over the millennia, contributed to the rich legacy of world cuisines we see around the world (and the Internet).

Well, coming back to my problem, unfortunately NO DIETS REALLY WORK on the long term. Being lean is based on many aspects other than food which includes heredity, mental health, endocrine health etc. A slight hint to be fit, though, is to remain active.

The celebrated 18^th century Malayalam poet, satirist and the founder of Ottamthullal School of art, Kalakkathu Kunchan Nambiar once said

"It is better to eat your heart out rather than to extend another 10 years of unhappy life in bland foods and medications."

He died of complications from diabetes after he attended a feast, ignoring the advice of his doctor. Neither he nor anyone else ever has documented his personal life. However, from his career as a satirist and love of food, he must have been a super happy man!

Motive of a Psychopath.

You might have heard about cold blooded criminals, who have no motive to kill and shows no remorse in killing or doing harm to others. In most cases they are called Psychopaths. You might picture psychopaths as ugly and scary but it is not like that. In most cases you cannot distinguish a psychopath from normal people.

A study shows that these psychopaths are born, not raised or victims of the situations that they face. These psychopaths has a smaller Prefrontal cortex(A part of brain which regulates behaviour, impulse control and planning) and a deformed Amygdala (A part of brain which gives us negative emotions like fear, guilt, and sadness).

There are three main Traits of Psychopaths

1) Fearless Dominance.

Since their Amygdala is deformed which gives them freedom from fear, anxiety or guilt. They can do anything without conscience, social consequences, authority figures or worrying about well being of others. They know the rules but don't care enough to obey it. They are charismatic and good at hiding their hard hearted self-assurance. They should not be mistaken as loner they do stand out because they are often liked by people because of charming, outgoing, charismatic and convincing nature. They lack empathy will not hesitate to hurt others.

2) Self-Centred Impulsivity.

Psychopaths need lot of stimulation that's why they go for extremities of the behaviour like starting fights, humiliating co-workers, torture animals, etc. Totally irresponsible, they do things because feel like it. They simply don't care what comes after.

3) Low Autonomic Arousal.

Psychopaths heart rate is lower. Their act of violence doesn't have rage at all. They get calmer with act of violence. Their physiology simply different than others.


This is why many argues that psychopaths are born not made by society they are born that way. Psychopathy is one of the most severe of all mental diseases. Though psychopaths are very dangerous and always commit heinous crime, they should be treated and handled properly.  Although they know what they are doing, but they do not know the reason behind that which means means rea(guilty mind) is completely absent in their act. Whatever crime or act they commit is due to their disease and not because of any guilty mind. This is a reason they never conceal their crime. They never show remorse of their action. There is not any sign of guilt or regret on their face whenever they are caught and they openly accept their criminal act without any repentant and sentiment. They always candidly accept their crime and desire to commit it again because of a strong urge to commit them which arises due to disease. 

Coding of Indian Locomotives

If you are a railfan or a train nerd like me, you must have wondered what those "WDP4, WAG9, WAP4 etc mean, at some point of time. Infact, they show a detailed specification of the "iron horse" that the train is being hauled by.

Let me explain them a bit:

The first letter (gauge)
W-Indian broad gauge (The "W" Stands for Wide Gauge - 5 Feet 6 inches)
Y-metre gauge (The "Y" stands for Yard Gauge - 3 Feet or 1000mm)
Z-narrow gauge(2 ft 6 in)
N-narrow gauge (2 ft)

The second letter (motive power)
D-Diesel
C-DC electric (can run under DC traction only)
A-AC electric (can run under AC traction only)
CA-Both DC and AC (can run under both AC and DC tractions), 'CA' is considered a single letter, very rare
B-Battery electric locomotive (rare)

The third letter (job type)
G-goods
P-passenger
M-mixed; both goods and passenger
S-Used for shunting (Also known as switching engines or switchers in United states and some other countries)
U-Electric multiple units (used as commuters in city suburbs)
R-Railcars

For example, in "WDM 3D":
"W" means broad gauge
"D" means diesel motive power
"M" means suitable for mixed(for both goods and passenger)service
"3D" means the locomotive's power is 3,400 hp ('3' stands for 3000 hp, 'D' denotes 400 hp more)
Or, in "WAP 4":
"W" means broad gauge
"A" mean AC electric traction motive power
"P" means suitable for Passenger service
"4" denotes that this locomotive is chronologically the fifth electric locomotive model used by the railways for passenger service.

Nowadays, we observe that WDP class locomotives are losing popularity. One main reason, which I can think of, is the smoke that they give out. It may get into coaches causing discomfort to passengers. With increasing electrification on railway networks, WAP class has taken over the passenger service to a major extend. However, WDM locos are being used for passenger service on very few remaining non electrified lines. Indian Railways has not yet released an official statistics on this.

On the other side, we see WDG locos going up the graph (especially WDG4 class). It makes sense that while IR is giving more priority to passenger service, they want a major share of load off the power grid by allotting lesser priority goods service to diesels (an exception being WAG9 class).

Why there is Colour Belts in Martial arts?

The colour of belts denotes the development of the martial arts students. It was not previously existing as you may think, but it was started being used around the start of 20th century. The colour also shows the ranks of the fighters.

The comfortable uniform of martial arts was introduced by Kano Jigoro the founder of Judo. He was a teacher by profession in his home country Japan. He started giving his students the belts. The lowest black belt rank was called 'Shodan' literally means beginning degree. 

In the beginning the students did not wear the uniform as it looks today but wore a Japanese Kimono with a wide belt called 'obi'. Jigoro introduced the modern uniform and its thinner belt in 1907. 

The colours were limited to black for experienced 'Yundasha' and white for less experienced 'Mundasha'. But this spread to other martial arts over time and became today's norm.

In karate, the belts also have deeper meanings assigned to them today: white represents birth and a new seed, yellow the sunlight that works on a new seed and begins its life, orange the power of the sun to help the seed grow, green is seen as the plant sprouting, blue is the sky the plant grows toward, purple represents the sky at dawn, brown the ripening of the plant, red is again seen as the sun and black is the darkness beyond it.

Foods that only millionaires can eat!

These are some of the foods that are meant only for those who have extra disposable income. They are very rare to find and hard to cultivate. But their taste are said to worth its value.Lets take a look.

Matsutake mushrooms.

Matsutake mushrooms, or mattake for short, are said to have been part of the Japanese diet for more than a thousand years. Despite this long history, however, no one has been able to figure out how to farm them, and they must be gathered by hand. Japanese matsutake are found under fallen leaves at the foot of pine trees, hence the name – matsutake means pine mushroom in Japanese.
while most popular fungi are enjoyed primarily for their taste, Matsutake are sought after for their unique aroma. The scent is both spicy and fruity, with a hint of sweet cinnamon. The fall feeling is completed by the mushroom’s pine-like earthiness.

The price can go upto $ 1000 per kilogram. Which is for good quality mushrooms there are cheaper ones too but the most important thin is the freshness of mushrooms. The main reason that they are expensive is that no one knows how to farm them they can only be collected by hands.Japanese matsutake are found under fallen leaves at the foot of pine trees, hence the name – matsutake means pine mushroom in Japanese.

Japanese Densuke Melon

A large black watermelon grown only on the northern island of Hokkaido. Because they are so rare, these melons can be extremely expensive. In 2008, a 17-pound Densuke watermelon was sold for $6,100, making it the most expensive watermelon ever sold in the country. The darker-skinned Toma watermelons are famous for their sweeter-than-usual taste in comparison to normal melons, and make popular gifts.

Japanese Wagyu Beef

Wagyu beef is intensely marbled with softer fat, has higher percentages of mono unsaturated fats, omega-3 and omega-6 fatty acids and is lower in cholesterol than commodity beef. The combinations of these fats deliver a distinctive rich and tender flavor compared to other beef. Some farmers go to great lengths of feeding the cows with their own hands, massaging them regularly for good subcutaneous fat distribution. They are given special food for good meet. And yeah this meat can come from Hyogo prefecture in Japan 

The most exclusive Wagyu in the world comes from Kobe, Japan.  People use the terms Kobe and Wagyu beef interchangeably in the U.S. thinking it refers to the same premium imported Japanese. Its Price is around $ 1300 per 16 Ounce Strip Steak. 

Kopi Luwak

Kopi luwak is the world’s most expensive coffee. The main factor of it’s high price is the uncommon method of producing such a coffee. It has been produced from the coffee beans which have been digested by a certain Indonesian cat-like animal called then palm civet or also civet cat. This is the reason kopi luwak is also called cat poop coffee or civet cat coffee. The feces of this cat will be collected, finished and sold as kopi luwak.

Although kopi luwak is a form of processing rather than a variety of coffee, it has been called one of the most expensive coffees in the world with retail prices reaching €550 / US$700 per kilogram, close to the €850 / US$1,100 price of Black Ivory coffee.

Black Ivory Coffee

 As same as kopi Luwak the only difference here is the Elephant.Black Ivory Coffee is a brand of coffee produced by the Black Ivory Coffee Company Ltd in Northern Thailand from Arabica coffee beans consumed by elephants and collected from their faeces.The taste of Black Ivory coffee is influenced by elephants' digestive enzymes, which breaks down the coffee's protein. "Protein is one of the primary factors for bitterness in coffee. Less protein results in a coffee with less bitterness." The coffee beans are digested, and are present with various other ingredients in the elephants' stomachs, which imparts specific flavours to the product. In contrast to civets who are omnivores, elephants are herbivores. Herbivores utilize fermentation to help break down cellulose (green leafy matter). Thus reduces protein and causes less bitterness.

One packet of coffee beans is $40.00 (will make 400ml of coffee) and is only sold in the store or by phone order (not available online).

Red Iranian Saffron

More uncommonly known as crocus sativus, saffron needs no further introduction. Its is also called the Red Gold because of it is costliest among all spices by weight. 

What is unknown to most users though is saffron’s rich history; its usage was first noted in a 7th Century BC Assyrian botanical almanac, but its roots go way deeper, having been sold for 4,000 years before its first recording.

Several historical VIPs have used saffron for its characteristics, including Cleopatra who dipped it in her baths as an aphrodisiac and Alexander the Great who believed it tended to his wounds. Saffron was also used for cough, colic and scabies. It cured the melancholy of Alexander’s troops, and they loved it so much that upon their retreat they brought it to Greece. Recent studies have shown that it is an anti carcinogenic agent, anti-mutagenic and immuno-modulating, and also has antioxidant properties.

But the foreigners who were initially exposed to saffron in their travels through Persia also feared that the Persians were using it as a drugging agent.

The market prices range from USD 1,100-11,000 per kilogram, with an average price on the Western markets at about $2,200 per kilogram. In the supermarket in Tajrish, customers pay around 3 Euros per Mithqal, which is 4.25 grams.

Madacamia Nuts

Macadamia is native to the East Coast rainforests of North Eastern parts of Australia. Several parts of mineral rich, tropical and subtropical areas of Australia, Hawaiian Islands, Middle Americas, Brazil and South African regions are favorite regions where these sweet and crunchy nuts grow in abundance.

Macadamia tree reaches to about 15 meters in height. In general, it achieves maturity and begins to produce fruit at around the age of seventh year of plantation.

There are at least about seven species of macadamia grown in their wild natural habitat. However, only two of which are edible and cultivated in the horticulture farms around the world. Macadamia integrifolia produces smooth-shelled nuts, whereas Macadamia tetraphylla has nuts with a rough shell.

The price of the world’s most expensive nut may be attributed to the fact that not only must a Macadamia tree be 7-10 years old in order to produce nuts, but also the incredibly hard shell of the nut must be broken prior to sale. The shell is so hard that it can actually break nutcrackers sold for home use.

So how much is this costly nut? Macadamia nuts can easily fetch around $30-$40 per kilo (2.2 lbs).

There are many more like Italian truffles, Caviare, etc. which is worth a fortune. So tune in to this site for more amazing stuff. Enjoy Reading.
