ScienceForDummies - Week 10 - Six Scientific Misconceptions Debunked

 Hello! The winner of today's vote was "Six Scientific Misconceptions Debunked". Though a tie (0-0), the lasy few weeks this was most popular.

1: Humans only use 10% of the brain

This is a popular misconception and a muth. We use our entire brain, but sometimes parts are just at rest. For some reason this is a well-spread "fact" but is a muth.

2: Lightning never strikes the same place twice

Lightning often strikes the same place more than one time. Certain machinery is made to attract lightning, so definitely, lightning does sometimes strike the same place twice, or thrice, or more.

3: Goldfish memory lasts three seconds long

Goldfish do not have extremely short spans of memory. They can remember things from quite a long time ago. 

4: The Great Wall of China

The Great Wall of China cannot be seen from actually what is considered space and it is basically invisible. The only human achievement we really can see from space is the lighting of cities.

5: Cracking knuckles = arthritis

Cracking knuckles has no harm nor benefit, nor does it cause arthritis. Nor does it weaken grip strength. 

6: Bats are blind.

Bats aren't blind, but their eyesight isn't their main sense - they use echolocation with their ears. Echolocation is a method of searching surroundings by producing a sound and hearing it.

ScienceForDummies: Electricity

 Hello! Today's episode is about electricity. Electricity relies on the idea of electrons. Electrons is a subatomic particle - a particle which makes up of an ato . It has a negative charge and there are sixteen of them in a single atom. So how do they relate to electricity? Electricity is a physical phenomena where something moves that has an "electric charge". This idea of electricity is related to magnetism, because it is related to movement. Simply, it is a type og energy that consists of the movement of electrons. Electricity generates an electric current, and things can conduct electricity to make it move faster and insulate it to make it slower.

ScienceForDummies: Heat and Light

 Hello!  Heat - Heat is an energy that is transferred from one body to another because of a difference in temperature. Heat flows from hot bodies to cold bodies ("bodies" meaning objects or matter). Hear energy is created when aroms move faster and collidep. It is also known as thermal energy, and heat is the transfer of said energy. Light - Light is a kind of radiation that can be perceived by the human eye. It has wavelengths which can differ, forming what we know as colors. It can travel, refract, reflect, diffract, interfere, and disperse, etc. These things is possible by light.

ScienceForDummies: Matter and Energy

 Hello! Today is about matter and energy, and the second week of the Physics series. What is Matter? Matter is a physical substance which occupies space and has mass, distinct from energy. Matter is physical, so it does not have a rational nor conscious nature, at least itself. The popular understanding is that there are three states of matter, which is true, though there are other things considered as states of matters, the most popular of which being plasma. Basically, matter is a physical object. But it says "distinct from energy". What is energy, then? What is Energy? Simply, energy is a capacity to do something, especially moving something else. Energy falls into two central categories: kinetic energy and potential energy. What is the difference between the two types? Kinetic energy is in movement, while potential energy is not used, but usable to work.
