Today while working I found that an M6 x 1.0 Thread bold will easily screw into a hole tapped 1/4"-28.
At first when I found this, I thought one of my boxes of bolts was labeled wrong, but I tried another set and it work.
Has anyone else come across this similarity before?

There seem to be a number of news stories coming out about the possibility of an imminent find of the Higgs Boson @ 125-126GeV:

So what if the elusive Higgs Boson is finally found? Could this somehow enable us to conquer and manipulate...
How to make a discovery in Physics/How to get in the "Physics Mindset"
Dear physicsforums,
Recently I've decided to take physics much more seriously, and - although this may sound lame - want to make a major discovery in physics. Ultimately, that's my goal. Don't tell me whether it's...
Oh hello. I'm quite uncertain about one of the reasons for the discovery of the neutron. Apparently, the neutron is supposed to be the radiation released by alpha particles hitting Beryllium. When the radiation hits Paraffin wax, the paraffin wax releases protons. At first, people thought that...
Playing around with Wolfram Alpha I discovered an elegant looking little equation. Judging by the decimal approximation of both sides, there seems to be an extremely high probability that it is true. A picture of the equation is attached but ill try to type it too...
Of couse this is unlikely to happen to me but
I was just curious that,
If a high school student genious or child prodigy like Jacob Barnett
discovered a pattern of prime numbers,
is (s)he allowed to submit his/her work to academia?
Hi PF
Does the discovery of the Higgs Boson mean anything to string theory ? Does it falscify or verify the theory, or is it completely irrelavant for the theory?

The following rumor has been spreading around the internet quite rapidly:

Is there any truth to this rumor? Does anybody have any insider...
Hi,
I am not a physics major, but attend a small university and am working on my PhD. I stumbled across something, and just accepted what I saw and went from there. It helped that I
1. accepted that we are all human and make mistakes
2. didn't know what had already been disproven
So I...
I'm currently researching for the term paper of my class on black holes and the topic I selected is the one in the title. I've found some good information so far, but I don't feel like I have enough to get an A without a bit more. I'm curious if anyone has any resources that would aid this...
Last chance to see Discovery in orbit!
Discovery has separated from the ISS and they can be seen in early evening (great for kids) in much of Canada and the northern part of the US over the next few days. Go to this NASA site and punch in your country, state/province, and select a city near...
Interesting historical paper
How Nuclear Fission Came to Be Discovered

I'm interested in the history of the discovery of the neutrino suggested in 1930 by Pauli and I read that the first clue came from the fact that beta decay energy from electrons had a continuous rather than discrete spectrum and this seemed to contradict the energy conservation law.

I swear I've read about these arsenic living organisms before NASA released this. I don't remember where but I know I read about it. Can someone else say that this was released before so I don't feel weird about it lol.

Apparently he thinks that if you threaten them, Discovery Channel can single-handedly solve all the world's problems.
I am having real problems fitting nuetrinos into my mental models of the world,when i think of strong,electromagnetic and gravitational interactions i find it much easier to work with because there's always something tangible i can relate it to,fermions,light or falling for example,but when i...
So I was just watching a naked science episode on discovery about pluto and how some scientists believe that it came from the hyperbelt. Now I would just like to clarify, does the hyperbelt surround our solarsystem? Like a ring around saturn? Or is the entire solar system surrounded by it? Like...

I'm finally getting around to reading this book I bought over 20 years ago, "The Discovery of King Arthur" by Geoffrey Ashe. Of course Ashe is a believer in the Arthurian legends being based on a real individual, so you have to take his assumptions with a grain of salt. It does have some nice...
Hi, what I did to try to find prime numbers was this (in a computer program)
Starting from 2, I set off a sine wave that has an amplitude=0 for every even number and an amplitude=1 for every odd number. What we are looking for, then, are the portions of the sine wave where the derivative...
Is there such a thing as a black star? Not black hole.
I read something from a national geographic magazine a few months back that was about an astronomical object. It was all black on the outside, emitted darkness instead of light, and it contained some water. It was some new discovery or...
As I read, this seems to be a tough question, even for Philosophers.
Other animals too do some maths concept. A prey understands concepts like bigger/larger/smaller concepts. If the number of predators are higher, it runs away. If it's smaller, it's tries to defend. It's possible that an...

I've been reading Brian Greene's book 'The Fabric of the Cosmos', and had a little trouble in the part where he explains bell's discovery regarding the EPR paradox.
Bell's discovery in short was that there is a way to check if a particle has a definite spin about more than one axis or not; He...

Hi everbody,
I am currently learning about the quark model in more detail, how the multipletts are constructed and so on. However, I wonder what particles were really found in that time? I found a list somewhere in the net stating:
1937: \mu
1946: K^0,\bar K^0
1947: \pi^-, \pi^+, K^+...

It is all but gone, economies will not fund space probes any more, we have cocked up, missed our chance, instead of discovery we have wasted our money on other things, think i am wrong? we shall see, but i predict that any space mission will be a piddling effort in the future.

Hi everyone.
I am trying to find out which is the first comfirmed discovery of an exoplanet. When I look on the web, I find some sources telling me it was the one found around peg51 by Michel Mayor and team in 1995, but others saying it was the one found around pulsar PSR B1257+12 in 1992...
