RIP Physicist Deborah Jin
It is with great sadness that the woman who I thought would eventually win the Nobel Prize in Physics, Deborah Jin, has passed away this past Sept. 15, after a battle with cancer. This one will truly hurt. She was in the prime of her life and her career. The Nobel Committee missed a tremendous opportunity to award a deserving physicist of her prize. -
The 2016 Nobel prize in physics
Congrats to three British physicists working at US universities who have won the Nobel Prize in Physics for revealing the secrets of exotic matter. Thoughts? -
Micromass' big October challenge!
Time for the October challenge! This time a lot of people sent me suggestions for challenges. I wish to thank them a lot! If you think of a good challenge that could be included here, don't hesitate to send me! -
Easy ways you can support Physics Forums
We are all members of an amazing community! It's chock full of science and math passionate people from all over the globe. However, "amazing" doesn't just happen over night or by itself. "Amazing" happens when members take pride and responsibility for the health of the community. Here are some basic ways you can improve and support PF... -
What's the feasibility of space mining companies?
Recently, I've been reading about those space mining companies (like Deep Space Mining and Planetary Resources), and from an amateur point of view, I thought that the overall idea was pretty interesting. But what's the feasibility of such a project? Are there any chances that we could develop this technology within the next decade or so? -
How would dark matter aggregate?
My only source of information on dark matter is popular science texts, like New Scientist. One thing that is never explained is how it gets to aggregate around galaxies. Lacking the ability to shed energy by radiation, it seems it should just fly straight past and through, never even getting trapped into an orbit. I can think of two possible explanations, neither very convincing... -
Is Desert Ever a Good Thing?
Cutting down rain forest causes desert, and this is viewed as an upset to the world's climate. What I'm wondering is whether any and all desert is basically bad, or whether some amount of desert somehow contributes to the health of the planet. In other words, if we exclude the man made deserts from consideration, would the natural deserts that exist be considered to have a positive effect on the earth... -
Biggest Science or Math Pet Peeve
Could be a common wrong definition or an ineffient way to solve a certain equation. I don't know, what in science and math bugs you? Educators should fill this thread! :D -
What will be the next big revolution?
Some say block-chain economies, some say driver-less cars and some say clean energy. What do you think? -
GAIA - 1 billion stars and counting
The GAIA telescope has been mapping stars in the Milky Way with unprecedented quality and quantities. It has been assembling the most detailed 3D map ever made of our Milky Way galaxy and has currently mapped over 1 billion stars. There are already hints that the Milky Way may be shaped differently from what we thought... -
Risk Index for Shared Components
In an earlier thread, Science Vulnerability to Bugs, I mentioned the case "Faulty image analysis software may invalidate 40,000 fMRI studies". In another recent case (can't find the link), an author decided to un-license his public domain contribution and withdrew it from publicly shared libraries, which broke very many products dependent on it. -
SpaceX Needs Us!
As already posted on PF, and you have likely seen in the news, a SpaceX rocket exploded, September 1, 2016. Elon Musk is reaching out for help in finding out how it happened. I already have my idea of what might have happened, but I want to let everyone else look for themselves to see if they can deduce anything. Some of the smart people at PF might be able to see something that the... -
Murray Gell-Mann on Entanglement
In this video Murray Gell-Mann discuses Quantum Mechanics and at 11:42 he discuses entanglement. At 14:45 he makes the following statement: "People say loosely, crudely, wrongly that when you measure one of the photons it does something to the other one. It doesn't." Do most physicists working in this field agree with the above statement? -
Relating integral expressions for Euler's constant
Thus is something you don't see in every textbook. A not so complicated method to relate integrals and limits involving Euler's constant. -
Micromass' big September challenge!
September, schools restart, summer ends, but a new challenge is here:
RULES:
1) In order for a solution to count, a full derivation or proof must be given. Answers with no proof will be ignored....
