This is certain. For more on this, see the thread : ...

I got as far as his shirt, then switched off.

Ah. So when you wrote "OP (Institute of Physics UK) who having concerns" you meant "with regard to teaching 12-year-olds, and only under certain...

Good answer. It gets to the heart of the matter. I've been trying to think of a reply to this thread, but nothing I could think of answers the...

It is only you that is going on and on about "an on-board energy store". No one else has signed up to that idea, whatever it may mean. It sounds...

No.

Well, as Blackadder would say, how dark is dark, I mean, just how dark do you want to be? I'm not sure most people would class neutrinos as dark...

Why should I watch this? ( anyone can make/fake a YouTube video afterall)

That is a good question. Hitler did not want the Japanese to attack the U.S. since he did not want to bring it into the war. He was well aware of...

An additional complication. U.S. was at war with Japan as a result of the attack. Germany declared war on U.S. on Dec. 11. If Germany hadn't done...

Where did the theoretical photon come from though?

auldbert That being the case I think store is a misleading word because it leads to the thinking that there is “on-board” energy related to the...

So something that can interact with light cannot observe that which doesn’t? I guess that’s what they’re saying. Edit: from universitytoday.com ...

To continue from last year, today is the 80th anniversary of the Japanese attack on Pearl Harbor. One can only wonder how history would have...

DM may be vast concentrations of ancient black holes from the beginning of the universe, according to a recent study. ...

Well if it doesn't interact with EM radiation it certainly won't cause effects that correspond to light behaving like a particle - it won't cause any...

As a member of the Institute of Physics, even if your claim is correct(*) and they are moving to that interpretation of kinetic energy as a teaching...

Except the evidence leads to this conclusion. The argument was that the term (not the concept) is outdated. That view is falling out of favour. ...

Once again Dywyddyr, thanks for your reply and my kindest regards for allowing me to express my views on this topic. I agree I have no evidence...

Do you mean from the Alpha Draconis star system or from underground bases here on earth? It would be reasonable to assume they influence politicians...

Hi Maurice, Your request is a few days old now, but I still want to answer you. I think the pre-poster is bothered by your English - but well,...

Just because we don't know what it is doesn't prevent us from quantifying it. Entirely beside the point. We can measure the height of a human in...

Thanks Dywyddyr for your reply and by the way I love your icon. Even particle physicists at the LHC see their accelerated protons as having on board...

How would you know if those pesky aliens aren't controlling our thoughts:lol:?
