Science
The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

What unit is used when finding height?
Usually it's feet and inches but you can use metres and centimetres too
What does the square cube law say and how does it explain the absence of giant ants on Earth?
If you increase the length of every part of an ant by a multiple x, the cross sectional area of its legs increases by a multiple of x^2 whereas its mass increases by a multiple of x^3. Thus the cross sectional area of the weight-bearing parts increases significantly less than the weight that it has to bear.
Which of the spheres measurements increases more the surface area or the volume?
If you increase the radius, the volume will increase more than the area.

Is the electromagnetic spectrum's wavelength scale linear or non-linear?
It's an absolute measure (like a ruler), you are not comparing it, in relation to anything else. So linear.
You could be any one of several numbers :- 6.291, 6.292, 6.293....and so on to 6.299
What would the world be like without pi?
The Physical world does not depend on Humans or the sciences to exist. Without the understanding of sciences (or mathematics) the infrastructure that Humans have built would not exist as it does today. If we had not grasped the "Concept" of Pi, then anything built utilizing a Circle or part of a circle (Arc) would have to be constructed via trial and error. All Circle related things would be very difficult to predict or understand...such as planetary orbits, etc.
Suzie and Mario had 12 apple each how many apple each?
If Person A has 12 apples and Person B has 12 apples, they both "each" have 12 apples. Total together, they have 24 apples.
To find the mean of numbers, add all of the numbers together and then divide them by the number of numbers there are.
For example if I want to find the mean of 1, 2, and 3. 1+2+3= 6 and there are 3 numbers that I am using to find the mean (1, 2, and 3). So I divide 6 by 3 and get 2 which is the mean.
What are the four fundamental math concepts used in evaluating an expression?
The fundamental math operations: 1. Multiplication
2. Division
3. Addition
4. Subtraction The operator performs the operations of the expression in the order from the left to the right.
Geometry was developed by ancient civilizations in Egypt, Mesopotamia, and the Indus Valley, among others. It arose out of the need to calculate measurements for purposes of construction, surveying, and navigation.
