What are the most fascinating science facts?

 Being an aerospace engineering student, I would like to share some facts related to my topic.

• There are only 3 ways to fly
  
  a. Be lighter than air

b. Push air down

c. Push any other substance down

---

• Convergent-Divergent nozzle (De-laval nozzle)

This is the type of nozzle used in fighter aircrafts and other aircrafts that can fly faster than the speed of sound. The air flow starts from the left side of the nozzle, reaches a maximum speed of Mach number 1(equal to sound speed) at the throat(the narrow middle part) and then accelerates to supersonic speeds in the divergent part.

• Propeller based engines are the most efficient form of aircraft engines at low speed flights.

---

• Most commercial jets such as Boing 747 or Airbus A320 use Turbo-fan engines, which are a combination of a jet engine with a fan at the front. This type of engines are very efficient at speeds of 60% to 80% the speed of sound, the speeds at which most commercial jets fly.

• Sound travels almost 18 times faster through aluminium than air.

• It is Impossible to send a single stage rocket to space with our current technology. That is every rocket that is used to deliver a payload to space has at least 3 stages.

What are the most fascinating science facts?

 1. If you accidentally eat a razor blade, there's no need to worry about the fact that the human stomach is highly acidic and can destroy a razor blade within 2 hours. But it is certain that the mouth will hurt.

2. Eating bananas can make you die because this fruit contains radioactive potassium. But calm down, humans need 10 million bananas at once to die from radiation.

3. Some types of marine animals such as turtles and salmon, are able to detect the earth's magnetic field by directing themselves. That's why they always find their way home. Unless they are caught by a fisherman.

4. Many people think that the main source of our oxygen is forested, in fact, the oceans contribute at least half of the total amount of oxygen on earth.

 1.

The burning zone of Candle in zero gravity is spherical in shape rather the elongated shape,cause there is no buoyant force for warmer air to rise above.

2.

Tardigrade are water-dwelling, eight-legged creature that can be grow up to 1.5mm. They are extremophiles (not true extremophiles) and survive even the gamma radiation and ionizations. They can live without water and air in space up to 30 years.

3. The slowest speed of light ever recorded was 17 metres per sec in 1998 by Professor Hau. Later on, a technique developed to stop it completely.

4. The object that is traveled farthest is Voyager 1 and it is still travelling already passed our solar system. It was launched on September 5, 1977 with the mission of carrying information related to humans, earth and our locality in universe for the extra-terrestrials to communicate us. It has traveled 139 AU (2.08E10 km) so any signal take 16 hours and 15 minutes to reach from earth to the spaceship!

5. Cymothoa exigua, or the tongue-eating louse, is a parasitic isopod of the family Cymothoidae. This parasite enters fish through the gills, and then attaches itself to the fish's tongue.

 Here it goes:

1. There are about 7,000,000,000,000,000,000,000,000,000,atoms in a human body.

2. Humans can't breathe and swallow at the same time.

3. Until the 1960′s, the only reliable pregnancy test was to inject a woman’s urine into a female African clawed frog. If the woman was pregnant, the frog would ovulate within 12 hours.

4. If you drilled a tunnel straight through the Earth and jumped in, it would take you exactly 42 minutes and 12 seconds to get to the other side.

5. The human brain takes in 11 million bits of information every second but is aware of only 40.

6. A teaspoonful of neutron star would weigh 6 billion tons.

7. Venus and Uranus are the only planet to spin clockwise.

8. Male koalas have 2 penises,female koalas have 3 vaginas(freaky!).

9. There's a blind man in America who uses echolocation to navigate in the same way as a bat. He is Daniel Kish.

10. Cats always land on their feet, thanks to physics.
