When an electron annihilates with a positron, the same amount of energy is before and after the annihilation: [math]2 m_e c^2=2 h f_c[/math] During pair-production a particle with a kinetic energy exceeding [math]2 h f_c[/math] (1.022 MeV) is needed to create an electron-positron pair. https://en.wikipedia.org/wiki/Pair_production fc - Compton frequency me - rest mass of the electron (and positron) Your body emits antimatter all the time. When unstable isotopes of carbon C-14 and potassium P-40 decay, antineutrinos and positrons are produced.

If I do something/anything you will say that hackers hacked into your computers and your cell phones etc. etc. etc. this is a public forum so we can't just write (because everyone can see) The biggest problem that scientists don't go into politics but some incompetents with humanitarian profiles. If you are a scientist you want to discover, not to rule people and order them around! If they are all your brothers and sisters, there is no point in wasting resources on armaments and on creating weapons to kill people.. ..at the moment people who are from another street are treated like strangers.. POTUS politics etc. etc. are obliviously accelerating antagonisms.. Reducing antagonism between warring nations would be the right thing to do.

It can work. The problem is that I would have to be "The Prime Minister Of The Planet Earth", "President of the United States of Earth", aka "God Jesus", etc. etc. I have some ministers from this forum who can help me @studiot @swansont @Phi for All

Brain in a vat, president, nice to meet you... Do you like squid shrimp and oysters?

..except he was banned from this website in his 1st term..

Since you created this object in 3D software, there should be no problem in showing how it works, i.e., generating an animated gif and posting it on this page so we can see how it moves. The problem with such objects is that they look good in 3D, but jam when printed and attempted to be used. Do you have a 3D printer or access to one to print this in real life? Making a simple screw and a long nut for it took a full day of modeling (>8h) and 3D printing >5 versions before it worked as expected and did not stuck.. I didn't want to read books on the subject (that would have taken even longer than the experiments!).. Try making a rubik's cube in 3D. Don't use downloaded ready-made ones or dismantle the real. All the “magic” happens inside..

POTUS complains that EU does not want to buy US food. Now reluctance will skyrocket dramatically..

Enter the equation in WolframAlpha, and the program will draw a graph and show alternative forms of the equation. https://www.wolframalpha.com/input?i=+a+%3D+(Pi+-+2)%2F4+%2B+sin(a)+ It has one obvious solution (t=0) and two non-obvious solutions. https://www.wolframalpha.com/input?i=+t%3D2sin(t)+

There are no countries fitting this criterion. I provided a link. There’s only one country over 20% https://en.wikipedia.org/wiki/Debt-to-GDP_ratio

If something is hotter than air, every atom on the surface emits energy into the air through infrared radiation or convection. The simplest way to dissipate energy is to increase the area that is in contact with the air. This is done by introducing partitions, irregularities, etc. Calculate the area of this thing if it did not have partitions compared to partitions like the one in the photo: It has a couple times higher area than without partitions. Radiator + air exchange fan is a typical configuration. The launching rocket does not need fans, as the air is replaced automatically. Increasing the area of contact between something that needs cooling and the air will result in faster cooling. This makes sense for a thing that is moving fast, such as a rocket taking off. Fossil fuel cars also do not need a fan on the radiator cooling the engine. The air coming into it from the front of a car going fast enough is enough. Your laptop will be accelerated to an abnormal speed while being thrown in the trash garbage can. If your question was whether it would be enough for me to statically cool my laptop using a heatsink when playing 3D games I would say that this is a rather poor idea. Unless you want to burn the CPU/GPU.

Maybe because of the units... Joule is kg * m^2 / s^2 so it has all three - mass unit, length unit and time unit..

I don't think I would have to, because any intelligent person would understand the OP.. It could be deduced from the context.. ..you have it in the title of this thread and OP.. Paraphrasing you - who is to judge who should get it, or not.. ? Knowing your political choices you wouldn't even give POTUS such credentials.. (so do I) You chose the POTUS so you got what you voted for.. so you have to live with it for four years (at least).. I don't see any problem with that.. This is silly. The hatred of the POTUS speaks through you. If POTUS (aka "TFG") wanted the data, he could simply ask Musk to his office and execute one line of code to download everything to a flash drive without any bothering about making DOGE etc.. Creating conspiracy theories by you? For real? HR hires and fires people at the request of senior management. Its job is not to optimize the structure. Unless it will be told to, but it was decided otherwise so it is what it is.. I think that Musk's group when reorganizing structures is more effective - after all, they have years of experience in this topic.. It speaks through you the dislike of TFG. Every POTUS wants to be an "executive".. and doesn't like to have his wings "clipped".. So does everyone.. This is usually done by looking for legal tricks to get around the law. The other side then makes other legal tricks to torpedo it. And this goes for years. Without or little things done. As if the Republicans undercut the wings of Kamala you would now moan how bad and stupid they are. If I see obvious foolishness and/or fraud I see obvious foolishness and/or fraud.. Harder is the case with some more twisted, more cleverly designed things. But I'm managing. I was talking about debts exceeding 100% GDP.. That's pity. Welcome to the new world of 2025. Wake up. Now you have the DOGE to optimize spending of gov.. You should be happy that finally the government will burn through less tax money.

Orban has been on Putin's leash all his life. Oil and gas from Russia to Hungary does not flow anymore. Now he has a chance to become a truly independent politician. Re-read Wikipedia link..

PiS ("Law and Justice") is not the far right... Far right burns Jewish flags in the streets, beats or verbally insults foreigners, etc. etc. From an economic point of view they ("PiS") are the equivalent of the US Democrats (increase taxes, take from the rich give the poor more money, increase government spending, increasing the impediments to doing business and taxing everything, increasing bureaucracy, etc., etc.). From a worldview point of view they are US Republicans (against abortion, against LGBT, two-sexes only, against migration, pro coal, gas and oil, human-made climate deniers, creation of laws that hinder the operation of RES., etc., etc.). Donald Tusk predates TFG by 30 years in politics. https://en.wikipedia.org/wiki/Donald_Tusk He was president of the European Council: https://en.wikipedia.org/wiki/Donald_Tusk#President_of_the_European_Council_(2014–2019) (who is the highest-ranking politician in the EU, if you are not familiar with the political structure of the EU) German chancellor, EU president, first-term POTUS in 2017. Too amused faces for the circumstances as far as I'm concerned - when POTUS talked about the termination of the climate agreement by the US.
