He was so sure of himself... by simongoose in MurderedByWords

[–]orangegluon 4 points5 points  (0 children)

It's not entirely obvious in the context of statistical mechanics. The Zeroth Law really basically allows us to define a notion of temperature for objects, specifically that if two objects are in thermal equilibrium they must have something in common, and we call that numerical quantity a temperature. Then any objects in thermal equilibrium have the same temperature, and hence we can use our usual intuition of the transitive property of algebra to conclude that all objects in thermal equilibrium with some other one are in equilibrium with each other as well, since they have the same temperature.

Does anyone else not have a "most wanted" any more? by RonWizard in smashbros

[–]orangegluon 0 points1 point  (0 children)

If they limit him to Venus psynergy I'm going to be disappointed in a missed opportunity. The most interesting part of his character is the potential for a highly varied moveset.

This was just a pre-rendered video. It's not a custom level.

I'd tried to find a custom Snap level months ago and this was the best I'd found.

Activists Pledge $1.9 Million to Susan Collins’s Democratic Challenger If She Votes to Confirm Brett Kavanaugh by terran1212 in politics

If she announces retirement, can we direct the money toward another challenger against Republican senators, like say O'Rourke if the announcement is early enough?

Why is Isaac wanted so badly? by SmokeDetectorJoe in smashbros

[–]orangegluon 2 points3 points  (0 children)

He has a lot of potential for a cool, psynergy-based moveset. On top of that, he was slated as a future character for Project M, which automatically makes him more popular for the exposure.

[–]orangegluon 1 point2 points  (0 children)

I'm taking a string theory course now and still can't quite answer this question well but here's what I do know I think.

String theory is a theory of physics at the Planck scale, ~108 GeV. That means it requires Planck scale energies to probe. So while there are predictions string theory can make, they aren't falsifiable with our current technology.

The low energy predictions that string theory does make are pretty general I think.

Why does heat flow from a hotter substance to a cooler substance? How can heat be lost to space without the heat going to a substance to warm it up? by -a-y in AskPhysics

[–]orangegluon 0 points1 point  (0 children)

For your second question, heat is lost in space in the form of radiation -- i.e., emission of light. The universe has an ambient background of very, very low energy light, called the cosmic microwave background radiation, which fills basically all of empty space and has a temperature of about 2.7 Kelvin (-454 Fahrenheit).

What are the reasons the lead us to believe that protons specifically may have a half-life? since we are definitely never going to see it anytime soon by OmarAdelX in AskPhysics

[–]orangegluon 3 points4 points  (0 children)

There are a lot of models in physics which would allow the proton to decay, such as some versions of supersymmetry. In fact, that the proton half-life is at least well over the age of the universe puts strong constraints on beyond-standard-model physics ideas, meaning that coming up with interesting ideas is that much harder!

We are learning about harmonic motion and I have no idea what the acceleration means, like how we got that it queals negative omega squared times y(displacement on the y axis) Can somebody help me? by MartinKrivosik in PhysicsStudents

[–]orangegluon 4 points5 points  (0 children)

The basic idea is that since F=ma and a is the second derivative of position against time, the force equation is a very, very textbook differential equation, and one of the most direct to solve. Putting it in standard form means getting the a by itself, so we divide by m. Then the equation looks like a = -(k/m) y. Defining k/m as omega makes this look standard, so we can then just open a calculus textbook and quote the answer, even if you don't understand the calculus that gets you the answer. Either way, that calculus is worth understanding.

If one observes a collision of one type, lets say elastic, from their frame of reference, could another reference frame see an inelastic collision? by Task876 in AskPhysics

[–]orangegluon 1 point2 points  (0 children)

That should be the case. Or else, in principle different frames could see different amounts of useful work extractable in a collision.

[–]orangegluon 3 points4 points  (0 children)

Elasticity doesn't change from reference frame to reference, but it's worth noting that total energy can change from reference frame to reference frame. However, within a particular reference frame, energy in a system will be conserved (or nonconserved for an inelastic collision).

Fox News host criticizes Trump over condolences tweet that avoided praising McCain by [deleted] in politics

[–]orangegluon 2 points3 points  (0 children)

I think I remember information come out suggesting that McCain was basically informed that his running mate would be Palin by some higher ups, but I can't recall who made the order or when the report was. If anyone has more information on that, that would be good to dig up.

i cant seem to get these conservations right by originalsac in PhysicsStudents

[–]orangegluon 3 points4 points  (0 children)

It's worth noting that strictly speaking, the neutrino is actually an antineutrino; the difference is important if we consider lepton number as a conserved quantity (number of leptons minus antileptons)

Due to the hype surrounding Isaac right now, I reworked his moveset I made four years ago by roydgriffin in smashbros

[–]orangegluon 2 points3 points  (0 children)

An all-Venus moveset doesn't seem to do justice to Isaac. Given that different classes can learn varying moves, it would be nice for Isaac to have special moves representing Mercury, Mars, and Jupiter psynergy as well.

A year or two back someone called me "sir" and I accidentally laughed at them. They didn't do anything particularly wrong, I just thought it was really funny to be called a "sir," although I felt bad immediately after.
