Jupiter Is The Really Bright One 🌝

the mathematics students

crisp, grey mornings

the scratch of pencil on graph paper

working through complex problems just for the joy of it

baroque era piano music playing in the background

a love of patterns and puzzles

writing out your favorite proofs again and again

advanced math courses, sitting with the upperclassmen

the dusty green of an empty chalkboard

formulas scribbled on your hand in pen

going through a problem again and again until you understand it fully

carefully sketched graphs

short, bitten nails

ice cold water

hands marked with graphite

using math to take apart the world around you

doodling fractals on scratch paper

memorizing digits of pi just to show off to your friends

the moment of clarity when a problem fits together

hair clipped back out of your face

looking for fibonacci sequences in nature

watching a long and complicated equation simplify down to something short and compact

‘Lost in Math: How Beauty Leads Physics Astray’ – A Review

Lost in Math is Sabine Hossenfelder’s book challenging physicists’ preference for elegant theories over experimental results. Discover how this can lead to dead end research that misleads the public. I have mixed feelings about YouTube. The good news about the video site is that anybody can start a TV channel there. The bad news is that anybody can start a TV channel there. There’s a tremendous…

hmmm

fuck it, its self indulgence saturday. anakin skywalker, but he was raised on mandalore, and also his mom is alive and well.

Alright.

Potential energy is energy debt borrowed from vacuum energy bank

Potential energy is defined as the energy difference between the energy of an object at a current position and the energy of the object at a reference position (generally, infinitely distant position) in a force field.

The gravitational potential energy of a combination of an object with mass M and another object with mass m separated by distance R is expressed by the following formula using the gravitational constant G.

The potential energy is zero when the distance between objects is infinite, and the negative energy increases as the distance decreases by gravity.

Because there can be no negative energy in the real space, potential energy should be considered as fictitious energy. Regarding potential energy as “energy debt” is easy to understand. Then what do objects borrow energy from? The answer is the vacuum space. Potential energy is the energy debt borrowed from “the vacuum energy bank”. An increase in the negative energy means an increase in the energy given by the vacuum space.

Therefore, the law of conservation of energy is established only when the vacuum energy is counted.

When an object is attracted to another object by gravity, a certain amount of energy is given to it from the vacuum space. Hence its energy debt increases by the amount given from the vacuum space, and its momentum energy increases then it accelerates.

On the contrary, when applying a force to an object and moving it against gravity, it returns a certain amount of energy to the vacuum space. Hence the energy debt decreases by the amount returned to the vacuum space, and its momentum energy decreases then it decelerates from the initial speed.

We say “potential energy increases” when the energy debt decreases, but we should say “potential energy decreases”.
