13 Interesting Facts about Dreams

1. You Forget 90% of Your Dreams
Within 5 minutes of waking, half of your dream is forgotten. Within 10, 90% is gone

2. Blind People also Dream
People who became blind after birth can see images in their dreams. People who are born blind do not see any images, but have dreams equally vivid involving their other senses of sound, smell, touch and emotion.

3. Everybody Dreams
Every human being dreams (except in cases of extreme psychological disorder). If you think, you are not dreaming, you just forget your dreams.

4. In Our Dreams We Only See Faces, That We already Know
Our mind is not inventing faces – in our dreams we see real faces of real people that we have seen during our life but may not know or remember. We have all seen hundreds of thousands of faces throughout our lives, so we have an endless supply of characters for our brain to utilize during our dreams.

5. Not Everybody Dreams in Color
A full 12% of sighted people dream exclusively in black and white. The remaining number dream in full color. Studies from 1915 through to the 1950s maintained that the majority of dreams were in black and white, but these results began to change in the 1960s. Today, only 4.4% of the dreams of under-25 year-olds are in black and white. Recent research has suggested that those changing results may be linked to the switch from black-and-white film and TV to color media

6. Dreams are Symbolic
If you dream about some particular subject it is not often that the dream is about that. Dreams speak in a deeply symbolic language. Whatever symbol your dream picks on it is most unlikely to be a symbol for itself.

7. Emotions
The most common emotion experienced in dreams is anxiety. Negative emotions are more common than positive ones.

8. Recurring Dreams
While the content of most dreams is dreamt only once, many people experience recurring dreams—that is, the same dream narrative is experienced over different occasions of sleep. Up to 70% of females and 65% of males report recurrent dreams.

9. Animals Dream Too
Studies have been done on many different animals, and they all show the same brain waves during dreaming sleep as humans. Watch a dog sleeping sometime. The paws move like they are running and they make yipping sounds as if they are chasing something in a dream.

10. Body Paralysis
Rapid eye movement (REM) sleep is a normal stage of sleep characterized by rapid movements of the eyes. REM sleep in adult humans typically occupies 20-25% of total sleep, about 90-120 minutes of a night’s sleep.

During REM sleep the body is paralyzed by a mechanism in the brain in order to prevent the movements which occur in the dream from causing the physical body to move. However, it is possible for this mechanism to be triggered before, during, or after normal sleep while the brain awakens.

11. Dream Incorporation
Our mind interprets the external stimuli that our senses are bombarded with when we are asleep and make them a part of our dreams. This means that sometimes, in our dreams, we hear a sound from reality and incorporate it in a way. For example you are dreaming that you are in a concert, while your brother is playing a guitar during your sleep.

12. Men and Women Dream Differently
Men tend to dream more about other men. Around 70% of the characters in a man’s dream are other men. On the other hand, a woman’s dream contains almost an equal number of men and women. Aside from that, men generally have more aggressive emotions in their dreams than the female lot.


13. Precognitive Dreams
Results of several surveys across large population sets indicate that between 18% and 38% of people have experienced at least one precognitive dream and 70% have experienced déjà vu. The percentage of persons that believe precognitive dreaming is possible is even higher, ranging from 63% to 98%.

AMAZING Facts about Formula1 Cars


• Do you know that 80,000 components are assembled together to make a F1 car? Even though these components are correctly assembled with 99.9% accuracy, it will still start with 80 things wrong.

• The deceleration and the retardation experience by the F1 driver when he pushes the brakes can be felt as if a normal car driver hits a brick wall at the speed of about 300 kilometer per hour.

• The F1 race cars can go from 0 to 160 kph speed and then back to 0 speeds in just 4 seconds.

• There are more than a kilometer length of a cable attached to as many as 100 of its actuators and sensors. Those are for monitoring and controlling various parts of the car.

• On an average the driver of the F1 reduces near about 4kgs of his body weight if he goes for just 1 race. This is because of the long time exposure of the high G forces as well as the temperatures.

• A F1 car is about 550kg in weight which is near about ½ of the total weight of a Mini.

• Aerodynamic design and the added down force is very much important. Just for an idea, take an example of a small plane; you know that it takes off at a speed slower than that of a F1 cars when it is on track.

• F1 race cars generally race at more than 300 kmph. If we do not have the aerodynamic down force, even the great racing cars which have sufficient power to produce the wheel spin will ultimately loss control at about 160 kmph.

• The down force has a tremendous power. Even in any street course race, it provides enough suction which basically can lift the manhole covers. Therefore, before the commencement of these type of race all manhole covers on the streets are welded from down in order to prevent from this mishap from happening.


• The refuelers which are used in F1 are able to supply 12 liters per second of fuel. Let assume that an average family car of 50 liter can fully filled in just 4 seconds. Actually they are using the refueling rigs which are now days used on the military helicopters of US.

• The top crew members of F1 can do refueling and change the tires both in just about 5 seconds. Amazing!!


• Every tire looses its weight during the race. It looses around 0.5 kg because of the wear.

A Formula 1 car has a phenomenal power-to-weight ratio – it weighs half as much as the average family hatchback but produces around 10 times the horsepower. Allied to cutting-edge automotive technology, that translates into breathtaking performance.

An F1 car can accelerate from a standstill to 160kph in around 3.5 seconds, while the sprint to 100kph takes just two seconds. During the 2004 Italian Grand Prix, BMW WilliamsF1 driver Antonio Pizzonia recorded the highest speed in F1 history – an astonishing 369.9kph.

Maximum braking from 200kph brings an F1 car to a standstill in a staggering 55 metres, a process that takes 1.9 seconds. Travelling at 320kph on a long straight, drivers can leave themselves just 100 metres and three seconds to decelerate to 80kph for a slow corner.

Downforce (or ‘negative lift’) is the key to the remarkable cornering speeds achieved by F1 cars. When an ordinary road-going car negotiates a corner, its lateral grip peaks at a little over 1g, at which point it begins to slide away.

An F1 car, by comparison, can generate upwards of 4g in high-speed corners. It is said that the FW27 generates enough downforce to stick to the ceiling at speeds of 160kph or more – although the theory has yet to be validated in practice!

Interesting facts about Snakes

King cobras make nests. Generally snakes show little or no parental care. But a pair of King Cobra will cooperate to find a suitable nesting spot. Nests are built usually in the month of April. Despite having no limbs, the female remarkably constructs her nest of dead leaves by scooping them up with her large body. Females then lay approximately 20-50 eggs, two months after mating, with an incubation period ranging from 60 to 80 days. The female will then lie on the nest until just before the eggs hatch, at which point instinct will cause the mother to leave the young so as to prevent her from eating them. The male king cobra is similarly unique in that he stays to guard the nesting area, until the young hatch, patrolling a large area around the nest for threats. Such complex nesting and rearing behavior is unique among snakes. No other snake shows any parental care.

King cobras eat other snakes. King Cobras eat almost all other snakes with the rat snake being it’s favourite. The King Cobra is peculiar in that it feeds almost exclusively on other snakes, which is reflected in its genus name of Ophiophagus (Snake eater). The King Cobra is known to attack larger snakes, including pythons. The king cobra's diet is mainly composed of other snakes. When food is scarce though, king cobras will also feed on other small vertebrates, such as lizards. After a large meal the snake may live for many months without another meal due to its very slow metabolic rate.

Snakes can survive without eating food for several days. Snakes have a slow metabolic rate and thus can survive without eating for many days at a stretch, after a sumptuous meal. Snakes like King cobras can survive many months without food.

Snakes are cold blooded. Snakes are cold blooded like all reptiles, with the exception of the Leatherback Sea Turtle, a reptile that elevates its body temperature well above that of its surroundings. Though cellular metabolism produces some heat, reptiles do not generate enough heat to maintain a constant body temperature and are therefore referred to as "cold-blooded". Instead they rely on heat from the environment to regulate their internal temperature, e.g. by moving between sun and shade, or by preferential circulation - moving warmed blood into the body core, while pushing cool blood to the periphery. While this lack of adequate internal heating imposes costs relative to temperature regulation through behavior, it also provides a large benefit by allowing reptiles to survive on much less food as compared to similarly sized mammals and birds, who burn much of their food for warmth.

Pit vipers use a thermal sensitive nasal pit to detect pray. Pit vipers are named after their specialized thermo receptors; heat-sensitive organs, located on either side of the head that look like small pits. These pits contain membranes sensitive to infrared radiation and allow the snakes to locate their prey based on temperature differences with their environment. To a pit viper, rodents and birds that are only fractionally warmer than the background stand out even in complete darkness. Like a primitive pair of eyes, these pits even give them depth perception, allowing them to strike accurately under such conditions.

Snake’s tongue is used to sense the surroundings. A snake smells by using its forked tongue to collect airborne particles then passing them to the Jacobson's organ, a special organ in the mouth for examination. The fork in the tongue gives the snake a sort of directional sense of smell.

Young snakes break out of their egg with the help of special “teeth”. A snake does not look after its eggs or take care of the young ones but leaves the eggs to be hatched on their own. The hatchlings or the young snakes therefore have special teeth to break open the eggs and come out.

Most snakes can climb trees. Rat snakes and pythons are excellent examples.

Snakes shed skin on a regular basis and it is a part of its growth. The process is called moulting. This is usually achieved by the snake rubbing its head against a hard object, such as a rock or piece of wood, causing the already stretched skin to split. At this point, the snake continues to rub its skin on objects, causing the end nearest the head to peel back on it, until the snake is able to crawl out of its skin, effectively turning the moulted skin inside-out. This is similar to how one might remove a sock from your foot by grabbing the open end and pulling it over itself. The snake's skin is often left in one piece after the moulting process. It is a usual process, essential for a snake’s growth.

All snakes are carnivorous. Snakes do not chew their food and have a very flexible lower jaw, the two halves of which are not rigidly attached, and numerous other joints in their skull, allowing them to open their mouths wide enough to swallow their prey whole, even if it is larger in diameter than the snake itself. It is a common misconception that snakes actually dislocate their lower jaw to consume large prey.
Snakes do not normally prey on people, unless startled or injured, preferring instead to avoid contact.In fact, the majority of snakes are either non-venomous or possess venom that is not harmful to humans.
Snake venom is a complex mixture of proteins and is produced by venom glands. Snake venom is highly modified saliva that is produced by special glands. Snake venom is a combination of many different proteins and enzymes. Many of these proteins are harmless to humans, but some are toxins. Snake venoms are generally harmless when ingested, and are therefore not technically poisons.

Snake venom is used to make anti venom & many other life saving drugs. An anti venom serum is actually a small quantity of the venom itself which when injected into an animal or human affects only slightly triggering an allergic reaction to it. The allergic reaction will allow anti bodies to be formed and thus immunity to the venom is developed.

There is no visible difference between a male and female snake. Snakes of either sex would look identical, the only difference being that of a hemipenis (plural- hemipenes) in a male and a cloaca in a female which is visible only on a deeper study.

Vipers have foldable front fangs. When not in use, the fangs are folded backward against the roof of the mouth. Vipers have a very affective system of injecting venom into its prey’s body. The hinged fangs are more intricate system that allows the snake to instantaneously strike, inject and withdraw from a struggling prey. The fangs are enclosed in a membranous sheath and can be folded backwards and upwards against the roof of the mouth. During a strike the fangs can swing forward and the mouth can open to 180 degrees.

Flying snakes only glide in the air, they can’t fly. They virtually swim through the air and can glide a distance of 100m. It can only glide by extending its ribs and pulling in the underside.


• The snake today forms part of the symbol of physicians and veterinarians (the snake is wrapped around Asklepios' staff), linking snakes to millennia of healing and medical practice.
• The hognosed snake (Heterodon sp.), grass snake and the spitting cobra can feign death by flipping on to their backs when threatened. They open their mouths, allow their tongues to loll and can empty a foul smelling substance from their anal glands, making them highly unappetizing to any potential predator.
• Many snakes, such as vipers, boas and pythons have temperature-sensing organs on their heads. These heat pits are sensitive to changes in temperature of as little as 0.002 degrees Celsius, and effectively allow the snake to navigate and hunt in the dark.
• Snakes can have over 300 pairs of ribs.
• Snakes turn "blue" before a shed. This opaque change to the skin is actually due to the presence of a lymph-like layer of fluid between the old and new skins, prior to the shed of the old skin.
• Reports of the longest, heaviest and oldest reptiles abound. Many cannot be verified. A reticulated python, shot in Indonesia in 1912, was said to be 32 feet 9 1/2 inches in length. One Burmese python weighed in at over 400 pounds. Although seldom as long as the giant pythons, the green anaconda is a heavier snake. Sir Percy Fawcett is said to have killed an anaconda measuring 62 feet in 1907, in Brazil. Since the early part of the last century, the New York Zoological Society has offered a reward of $50,000 for the capture of a live snake greater than 30 feet in length. The oldest recorded snake is a boa constrictor named Popeye, who died in 1977 at the age of 40 years, 3 months and 14 days.
• The smallest snake may be the Martinique thread snake (Leptotyphlops bilineatus), which does not grow any bigger than 4 1/4 inches.
• A snake's internal organs, although superficially different, have basically the same functions as those of a mammal. The difference lies in their arrangement. They are placed one after the other, to accommodate the tube-like body. All snakes have a right lung and associated air sacs that extend most of the way to the vent. In most species, the left lung is considerably shorter, or even missing.
• The glottis, which is the entry to the trachea (breathing tube), can move to either side, to allow the snake to swallow prey. This is the tube you see when you look at the floor of a snake's mouth. Cartilage around the opening of the tube closes to prevent food from entering the respiratory tract, and produces the classic "hiss" in many snakes.
• A snake's heart can slide 1 to 1 1/2 times its length from its normal position, to allow the passage of swallowed prey. This is because of the relative mobility of the pericardial sac, which surrounds the heart.
• Venom glands have evolved independently in several species. Venoms are very complex substances, which may consist of a dozen or more toxic components. These can include substances poisonous to the heart, nerves and DNA as well as enzymes that break down natural tissue barriers, allowing the spread of venom within the body.
• Spitting cobras can inject venom in their bites, but can also force venom out, under pressure, through tiny channels in their fangs. Raising the front half of its body, the snake can aim venom at the eyes and mucous membranes of its target, over 3 feet away.
• Snakes have two rows of teeth on the top jaw, one row on the bottom jaw. The teeth, including fangs, in most cases are replaced throughout life.
• When the tongue is in the mouth, it lies in a sheath beneath the glottis with its tip touching the vomeronasal or Jacobsen's organ. This is an organ of smell, so when your snake flicks out his tongue, he is, in fact, "tasting" or smelling the air. The forked design allows the snake to detect on which side the smell is strongest, and so to locate his prey, even in the dark.
• The Brahminy blind snake are all females. When mature, they lay fertile eggs, and the young are clones of the mother. Although native to Asia, this snake is now found in warm countries all over the world.
• The Emerald tree boa is born red or yellow, and changes to green after about a year.
• The rattlesnake's rattle consists of six to 10 layers of scales, which fail to shed and make that distinctive sound when the tail is shaken as a warning. Eventually the older segments will slough as the rattle lengthens.
• The tail of the Calabar ground boa is blunt, cylindrical and has white scales on the underside, and altogether appears very much like a head. When threatened, the snake coils into a ball, hides its head, leaving the less vulnerable tail exposed to confuse predators.
• The common egg eater (Dasypeltis scabra) is a highly specialized snake. Although it is not venomous, the markings are sufficiently similar to those of the deadly cobra or viper that a potential predator will think twice before attacking. The egg eater can also expand its jaws to mimic the larger head of the venomous. To consume an egg, the jaws can expand to four or five times the size of the egg. Once engulfed, the egg is pierced by two specialized vertebrae. Other modified bones in the vertebral column stabilize it, prevent its slipping out of the mouth or further into the snake. Yet another set of unique vertebrae crush the egg. Once emptied of its contents, the shell is regurgitated.
• The black mamba (Dendroaspis polylepsis) is brown, gray or olive, but never black. It is a particularly dangerous snake, with a bite that kills 95 to 100 percent of victims. The black mamba may also be the fastest snake, reaching speeds of 10 to 12 miles per hour. Other particularly dangerous snakes include the common krait, Russell's viper (both Asian snakes) and the taipan (Australian). Seven of the 10 most deadly snakes live in Australia.
• Snakes move by relaxing and contracting muscles lengthwise along the body. Sidewinding is a specialized form of motion that allows a snake to travel with speed and relatively little expenditure of energy along loose desert sand. The snake lifts a loop of its body from the surface, using its head and tail. The loop is moved sideways and then back to the ground. This creates the typical series of unconnected parallel tracks.
• The paired claw-like structures seen on either side of the vent of a snake such as a ball or royal python, are in fact, remnants of the legs present in the animals from which the modern species has evolved.

Interesting Facts About Mars

This magnificent planet has been major candidate for the science fiction movies for many decades. When we consider all the facts it is impossible to imagine that any life could exist on Mars. However, scientists believe that straight lines on Mars are evidence of ice deposits underneath the planet's surface.

The strange belief, based on Mayan studies, is that Martians fled their planet and landed on Earth (some believe that Mayans descended from Mars). Today Mars is made up of iron with largest volcano in our Solar system called Olympus Mons (see photo bellow) and largest canyon Valles Marineris, which is 2,500 miles long. Mars has two moons and scientists believe that the moon Phobos will crash into Mars in less than 50 years.
