This is a basic conundrum that has bothered me for years: if you or a species like you is "adapted" to Twice Gravity (or any other multiple of 9.8m/2 squared) and your life functions and capacities are near identical, How strong/fast are you? Compared to 1G? See, this is the issue of mass vs...

For example: https://www.laserfocusworld.com/test-measurement/research/article/16566273/scientists-develop-saseran-acoustic-laserthat-produces-terahertz-sound-waves Can these devices produce ionizing radiation? I understand ultrasound traditionally does not produce ionizing radiation, but I am...

I'm trying to understand if the amount of effort/energy required to get to absolute zero approaches infinity, or if its a linear thing... is there a point in which dropping near 0 kelvin changes from a 1:1 to an exponential curve? Is the whole thing a curve or is there a static point, like 1...

Wiki said "Arnold Sommerfeld calculated that, for a 1s orbital electron of a hydrogen atom with an orbiting radius of 0.0529 nm, α ≈ 1/137. That is to say, the fine-structure constant shows the electron traveling at nearly 1/137 the speed of light.[9] One can extend this to a larger element with...

Hypothetical scenario and I'm trying to understand the velocity of the air as it tries to equalize with a large vacuum. I presume this model isn't very much different from an initial loss of 1 atmosphere pressure in space via some puncture. I'm mainly concerned with the immediate wind speeds and...

From a grinding wheel, I'm able to intuit that as an object increases in speed, the amount of friction inch per inch is constant, while the total friction occurring per second increases, and that increases heat, which can lead to friction welding. So I am trying to understand the other...

right, so a simple machine comparison, let's revise how this is being asked, as briggs seems closer to what I'm asking. if you had an axle with a radius of 11" and a wheel of radius 12" wrapped around it, (11/12) (no ball bearings), so you have direct contact, and friction as the wheel rolls...

So say I've got a wheel who's outer radius is 12" and the radius of the axle is 1.5", so the simple machine here is an 8 to 1 ratio. So I am wondering, since 1/2mv^2 is for kinetic energy, and the velocity here is 1/8th, does it mean the friction is 1/8th or 1/64th? does it get 1/8th hotter or...

Recently the media had a buzz about the testing of spiders ballooning on electrostatic or magnetic and wind currents. Scientists were able to cause the spiders to lift and descend by changing the electric field in the air. So I'm wondering, if that's true then does the "wing" (in this case fine...

I was taking notes recently for delta y/ delta x and noticed there's more than one way to skin a cat... or is there? I saw the leibniz dy/dx, the triangle of change i was taught to use for "difference" Δy/Δx, and the mirror six ∂f/∂x which is some sort of partial differential or something...

ok, so, to clarify vertical rule applies to y = f(x) = x^2+x^4+x^6... y = f(x) = x^1+x^3+x^5... or a combination of any of these, and because they are not subject to a horizontal rule, they are still functions... But, horizontal rule applies to x = f(y) = y^2+y^4+y^6... x = f(y) =...

https://ibb.co/nOQSES here's a comparison graph of what my brain was thinking but had turned 90 degrees. So do functions of y exist and do the rules for non functions remain vertical lines or do they switch to horizontal lines?

ah, i was thinking with a rotation of 90 degrees with my x and y reversed (in blender Z is vertical and X and Y are subjective) f(y) doesn't work with the above formulas if a function is canceled by a vertical line. for example: x = y^3, x = y^1, x = y^3+y^5, x = y^3+y^7 all of these produce...

So if i take the rules that a straight vertical line drawn through the function with more than one intersection implies it is not a function, to mean that the quadratic equation for a circle is not a function. Furthermore, it also implies a cubic equation, such as x^3 can be a function, because...
