50 SIMPLE SCIENCE FACTS EVERYONE SHOULD KNOW (BUT DOESN’T) #2 (11-20)

11. Red and yellow, kill a fellow… : …red and black, friend of Jack. This mantra helps amateur and professional naturalists alike tell the difference between the deadly coral snake and the entirely harmless scarlet kingsnake. 
12. Spiders are not insects. : Many people lump spiders in with the insects, but their eight legs, simplistic eye structure, and lack of wings do not place them in that classification. Rather, biologists consider them arachnids, related more to scorpions and ticks than wasps and ants.
13. Dolphins and whales are not fish. : Because of their shape and aquatic habitat, people continuously mistake dolphins, whales, and porpoises as fish. As endothermic creatures with hair, mammary glands, and the ability to give birth to live young, they fully qualify as mammals – specifically, cetaceans. 
14.Bats are not birds. : Due to the fact that they actually fly rather than glide, many people still adhere to the belief that bats are birds. In reality, their hair, endothermic body heating, milk production, and giving birth to live young land them squarely in the mammalian classification.
15. Never put a magnet near electronics. : According to Argonne National Laboratory – among many, many other reliable sources, of course – magnets and their accompany fields can negatively interfere with or outright damage most electronics.
16. Frozen water is capable of cracking metal containers. : State Farm Insurance offers up some great tips on preventing bursting plumbing in a home, which affects up to a quarter-million families a year in the United States alone. Even though cold contracts, the act of freezing water creates a solid with the dangerous ability to split open even metal confines.
17. A light year is not a unit of time. : Although the term “year” factors into the nomenclature, a light year actually measures extremely long distances and is used in mapping galaxies, planets, stars, and other astronomical phenomena. NASA states that light years are equivalent to about 9,500,000,000,000 kilometers and stem from how quickly a beam of light will travel in the span of a year.
18. Heat expands. : Heat causes the atoms and molecules of a substance to vibrate more, and subsequently expand as a result. 
19. Cold contracts. : Boston University provides some great information on how cold contraction works when juxtaposed with heat expansion, providing all the necessary formulas to illustrate the point.
20. Antibiotics can render birth control pills ineffective. : According to the Mayo Clinic, antibiotics do have an effect on whether or not oral contraceptives work – however, their true risk has been a bit overblown. Those on low doses especially need to consider alternate forms of preventing pregnancy, though it is a wise idea for any woman on birth control pills to do so if antibiotics are needed. Rifampin has already been proven to negate their efficiency.

50 simple science facts that everyone should know #1 (1-10)


Despite what some may say, science is not an inaccessible discipline (or, more accurately, series of disciplines) exclusive to academics. But due to this perception, many basic elements of the various scientific fields become warped, perverted, or switched over time and gelled in the minds of the populace as absolute fact. While obviously not everyone remains ignorant of the realities behind the myths, it is the sad truth that many of the following facts remain entirely obscured in the common consciousness – victims of myth and misconception in spite of reliable evidence to the contrary. This list compiles many frequently overlooked or misunderstood elements of science and backs them up with research from university or government sources as tangible proof.

1. Water is an excellent conductor of electricity. : While data on deaths and injuries resulting from the potentially fatal combination of water and electricity is extremely difficult to find, it remains a sadly common accident. 

2. Do not mix ammonia and bleach together. : While death does not generally factor into the equation, blending ammonia and bleach together releases extremely harmful chlorine and other noxious gases that can cause serious damages to the lungs and brain – if not outright kill, of course.

3. Acid into water, never water into acid. : The reliable mnemonic relating the procedure to A&W Root Beer helps students and chemists alike remember that the opposite effect may result in painful or disfiguring chemical burns. 

4. What goes up, must come down. : Anyone shooting a bullet or other dangerous projectile straight into the air ought to think towards one major aspect of Newton’s Universal Law of Gravitation.

5. An object at rest stays at rest… : …because of Newton’s First Law of Motion. Put simply, a resting object will not begin moving until another one places some sort of force upon it.

6. An object in motion stays in motion… : …also due to Newton’s First Law of Motion.

7. Matter is neither created nor destroyed. : Burning an ex’s stuff in a supposedly defiant display of independence and vengeance will never make it actually go away thanks to the Law of Conservation of Matter. As matter is neither created nor destroyed – but rather changes state –.

8. Energy is neither created nor destroyed. : As with matter, energy only changes between different states rather than spontaneously popping in and out of existence. Its official name – First Law of Thermodynamic

9. What constitutes a chemical change. : Chemical changes – such as burning, cooking, decomposition, and others – permanently alter the composition of an object. 

10. What constitutes a physical change. : Unlike chemical changes, those of the physical variety (cutting, carving, breaking, etc.) only alter the shape or form of an object and leave their core compositions intact
