That's a nice one.

I use procrastination, rather than predestination, when it comes to matters of belief.

More comments: In special relativity it doesn't make sense to talk about a constant force. It's a constant 4-force what plays the role of a "constant push." In those conditions, velocity doesn't grow indefinitely; it tends to a limit, the speed of light in vacuum. It's called hyperbolic motion. Also, you should clarify whether you mean coordinate time or proper time.

Wait a minute. That's right. What derivation?

That was me.

Back to lemurs, then. As all primates use tools.

🤣

Then it definitely isn't "the optimal description of Nature." The equation is also dimensionally inconsistent. Then you have an indetermination of the kind \( 0/0 \). It still has nothing to do with \( E = mc^2 \). Solving it is not difficult, but it makes no physical sense.

Nice video. Is that a Brooklyn accent?

The devil is in the details. Show us some, please.

🤣 Happy Festivus.

I don't think Zaps, or John, are trying to get you banned. Sounds to me that they're trying to corner you logically. That is always something most people of reason, always in our hearts, thank our intellectual opponents for --or should--, and deeply regret if we ever don't, and get carried away. It's actually the highest compliment you can get from people like them or like me. It's like having it said to you: "You are no idiot, I'm sure somewhere in there is a reasoning agent". I think you came closest to getting banned when you decided to drop reason and started applying names to other users (namely, myself and John, "fools"). You got it completely wrong. We'll never give up on you as long as you try to use reason and evidence, if I know what their motivation is. And I think I do. I'm sorry, but the Bible, although a beautiful at times, valuable always, document, is not a valid source of reason and/or evidence in general.

You're absolutely right. I tried to convey that with, The energy dependence you're referring to would indeed be reflected in the \( \int d^{4}xe^{ipx} \) integrals, to which you'd apply the cutoff \( \Lambda \) for the given energy range. So, as you say, it'd be something like, \[e^{4}f\left(m/\varLambda\right)\] I was kinda fixing this temp-dependent factor, or normalising it to 1, if you will. At that energy, the \( e^2 \) terms would totally dominate the photon-photon ones. Low-energy photons are never seen to scatter off each other at room temperatures, let alone at cosmic-background energies.

For whatever reason, a question that has been in my mind for many years, "what ever happened to Laika?", popped up again yesterday. Maybe it's because I tend to feel sad in Christmas. It's a recurring theme for me. Christmas seem to be all about loss. And I'm a Cold-War kid. In recent years I've learnt from paleo-anthropologists that we probably owe much of what we are to the presence of dogs in our lives, that goes back tens --if not hundreds-- of thousands of years at the very least. https://phys.org/news/2019-02-prehistoric-humans-dogs-death.html We owe them so much. Anyway, I found this story answering all my questions. It's not a happy story, I must warn you. https://www.smithsonianmag.com/smithsonian-institution/sad-story-laika-space-dog-and-her-one-way-trip-orbit-1-180968728/ I always wanted to know what ever happened to Laika. Merry Christmas

The QED matrix element for this process "goes like", \[\textrm{Tr}\left(A_{\mu}e\overline{\psi}\gamma^{\mu}\psi A_{\nu}e\overline{\psi}\gamma^{\nu}\psi A_{\rho}e\overline{\psi}\gamma^{\rho}\psi A_{\sigma}e\overline{\psi}\gamma^{\sigma}\psi\right)=e^{4}\textrm{Tr}\left(\cdots\right)\] There are space-time integrals involved, but roughly speaking the probability for this process is controlled by the number, \[e^{4}\sim\left(\frac{1}{137}\right)^{2}\simeq5.328\times10^{-5}\] Which, again roughly speaking, means that this process of photon-photon scattering takes place 5 times every 100'000 times photons cross paths. The internal legs of the diagram represent two pairs of virtual e, e- pairs once appearing and once disappearing, and two processes of electron-photon and positron-photon scattering. At large enough scales what you see is photons scattering off each other every once in a blue moon.

Going backwards in the Punnett square, taking into account possible restrictions on the parental generation (wild types, homo-/hetero-zygotes, etc.) https://en.wikipedia.org/wiki/Punnett_square#Dihybrid_cross

Why do you write "Dog" with capital D? Is this some kind of palindromic play with words? Why can't you reincarnate into a bat, or an eland, or a moss? Does it have to be a domestic mammal?

Sure it would in principle, those would be focalised beams of photons that would meet those completely thermal photons, here and there. But the chances of two photons scattering is completely negligible in QED at given temp. It is this process: https://en.wikipedia.org/wiki/Two-photon_physics

You can treat the EM field classically; then there is a particular configuration that is consistent and is made up of an E that gives rise to a B, that gives rise to an E, etc. without any charge density sustaining it. Those are so-called "vacuum solutions" of the Maxwell equations and correspond to radiation, any EM radiation. The CMB is made up of these EM waves in the vacuum. They are clearly distinguishable from static fields. The quantum picture is one of photons, of course. The CMB is an EM field, but it's completely thermalised. So it's not like the light from a light bulb, or from the Sun, or from a diffraction grid, let alone from a laser. It has no particular direction, and has a considerable dispersion in frequencies. But most of the photons are around, \[\frac{\hbar\omega}{k_{B}T}\sim1\] in frequency \( \omega \) for \( T = 2.7 K \) of absolute temperature, where \( k_B \) is Bolzmann's constant. so it's very cold. You can shield almost perfectly against EM fields by using a conductor.

Nobody said that. You don't want to learn science, that's all. Nobody said "any matter whatsoever". See how you are intellectually dishonest? Doesn't your Bible tell you not to bear false witness? You put words in other people's mouths. Now, that doesn't surprise me, really.

Swansont's points well taken. Also: That's not an integral equation. There's extensive work in mathematics about how to solve integral equations. In what variable? Do you mean, \[ F\left(t\right)=\left[M+F\left(t\right)\int_{0}^{t}v\left(t'\right)dt'\right]\frac{v\left(t\right)}{t} \] as an equation for \( v \)? But \( F \) depends on position. What happens at \( t=0 \)?

Ferromagnetism,* superconductivity, and superfluidity are among quantum effects that can be seen with your own eyes. It is true that the context of QM par excellence is the very small, though. That's due to the smallness of the quantum of action when compared to ordinary experience. * https://en.wikipedia.org/wiki/Ferromagnetism#Explanation

Agreed. And it's the bizarre nature of your questions. If you keep going on like this, you'll never get around to mathematics. I cannot emphasize enough how much attention you must pay to these tips: I could hardly agree more. If you're trying to climb Mt. Everest, and you're looking at another summit in the distance, you're gonna fall through a crack. Does that make sense? And for Pete's sake, solve a simple linear equation, get pleasure from it, and step on towards a more difficult problem. And keep going. Get something under your belt, however modest, ASAP. No matter how simple. Edit: Oh, and another thing. You're getting excellent advice here. Don't pay heed to "Daft Science" or "CrackpoGenius" or similars who might tell you how much more intelligent than others you are. They're distracting you and you've gone astray by their compliments before. I've seen it happen. That's another crack in Mt. Everest. Compliments are very distracting. Reliable information is gold.

I did take a look at your channel, I don't obligate you to anything, and I do not have the power to ban you nor any will to do so. I agree with @studiot that it's a good example of a very bad simulation of science. If you care about these things, you should take time to learn them. Pressure does not require contact. We understand today that contact forces do not really exist, in the strict sense. It's all fields. You seem to ignore also that there are models of QM based on particles following the Hamilton-Jacobi equation with a quantum potential. They reproduce all the kinematical results. It's not that you don't understand pressure, or interactions monitored by fields, etc. It's, as very often happens in the realm of crackpottery, that you couldn't care less. You should open your ears and you could learn something in these forums from other users who know more than you. I have.
