Facts about Sciences
You wouldn't die from suffocation if you were unprotected in outer space.
Before you could suffocate you would explode, because there is no air pressure. |
A sphere actually has two sides.
There are, however, one sided shapes, like the Mobius strip. |
Mathematically, less raindrops fall on you, if you run in the rain.
|
Snow is a good insulator and can keep objects warm as well as cold.
This is why igloos are so warm and even fires can be lit in them. |
|
Not only do positive and negative charges attract, but positive and neutral attract, and negative and neutral charges attract.
|
A constant speed of sound does not exist.
Sound travels differently depending on temperature and the medium it is traveling through. |
|
It is not equally likely for the outcome of a coin toss to be heads as tails.
The heads side is heavier and will fall to the bottom. The actual ratio is 4950 heads out of 10 000 tosses. |
Eurofighters do not need afterburners to sustain supersonic flight.

Literacy rates have not changed a significant amount since WWII.
Some studies show that literacy has not changed at all, and a few show that the rates had actually dropped a very small amount. |
Not all radiation is harmful, as light is a form of radiation.
All parts of the electromagnetic spectrum are technically radiation. Only gamma rays and x-rays are harmful. |
|
In space, red objects are not always hotter then blue objects.
The colour does not always mean the temperature, but also the velocity of the planet and its chemical makeup. |
Transgenic salmon grow faster than other salmon, but in the end they are not bigger.
Transgenic salmon do not have a size advantage over the natural fish. |
|
Not all planets spin in the same direction. Venus spins the opposite way than the other planets.
|
Mobile phone interference has never caused a death at any hospital.
Sometimes alarms were set off or cardiac monitors were innacurate. Tests showed anywhere from 4%-0% interference rates. |
|
A penny thrown from a tall building would not kill anybody- the most that could happen is a really small bruise.
Pennies are not very aerodynamic and would not gain enough speed to hurt anybody. |
Velocity and speed are not the same thing.
Velocity is a vector, it has both magnitude and direction, whereas speed only has magnitude. |
