By Homoeopathic, i refer to the quackery of taking a solution of water and an active ingredient, and then diluting it to such a degree that it is the equivalent of having one molecule of the active ingredient in a volume of water described by a sphere of radius 150 million kilometres! Ah but the water remembers that the ingredient was there...which by logical deduction means that it also remembe

When you say sparkling cider, I presume that this was alcohol free cider i.e. fizzy apple juice.
Also, just to play devils advocate, the punch sounds like it was loaded with plenty of sugar and E numbers. How do you know they were not just effected by this content, or indeed the excitement of a party, as opposed to the power of suggestion.

Hi Rick,
Forgive the questions, and know that I ask them with respect and in teh interests of discussion.
How did you know that you were given the placebo, given that in most trials not even the researchers now which subjects get the drug and placebo, until after the trial is over.
How do you know you were not subject to the so called placebo effect during your trial?
Also, how do you

Hi Don,
I think the term "fraud" is rather strong, as it implies a deliberate misleading. I also think that the title of the article is also rather sensationalist.

This drug has a complex organic formula specifically e

For the problems of installing a newer version of XP see here. All you need to do is match the service pack number to teh one on your computer, and you will be able to overright the windows files, as it should recognise it as the same version, despite further installed updates or hotfixes.

These low budget techniques often get the best results. I had an optical table built out of paving slabs and ceiling tiles to isolate vibrations on a microscope (optical table £20,000, building material from B&Q to make my own, £20). Our lab was in direct competition with our collaborators in Cambridge to see who could use the most "Village" piece of kit and still get good data.

Indeed, and this is why the effects of relativity are so anti-intuitive to people who first come across them, because they have such little impact upon our everyday lives. Now if we all whizzed around at appreciable fractions of the speed of light, or if the speed of light was much less, such effects would matter. However, the result is important as this is the first time that relativistic effec

Things can escape from the vicinity of a black hole no problem, as long as the object is not below the event horizon, which marks the point of no return. So if you were outside the horizon, you could get away from the beast, if you could obtain a significant velocity. However, the event horizon marks the point at which the escape velocity at that point is equal to that of the velocity of light,

For those who are interested, here are a series of interviews from the BBC archives (recorded in 1983) where Richard Feynman discusses how to picture and imagine what happens in physical processes. You can see the sheer pleasure of Feynman as he discusses even the most simplistic of things, such as a bouncing ball. I hope you enjoy.

Hi Don,
If you have the original XP disc you can use a free downloadable program called Nlite, to slipstream a new bootable disc, AND incorporate all SP2 or SP3 onto that disc (and subsequent updates), as well as all non-generic and generic drivers for your computer, and any other programs that you wish to include (extra browsers, adobe reader etc. This means that you can turn an old pre-serv

It depends on what one means by the term smallest. Electrons are thought to be point objects, and hence have no size (at least in any theory that we have experimental evidence for). But then again, the same goes for quarks. However, both quarks and electrons have "spins", and are charged, and so will have magnetic moments. So technically, they are both the smallest magnets.

Hi Sansahansan,
It all comes down to how close an object comes and its mass. Remember that the force of gravity between two bodies increases inversely with the square of the distance between them. Also, the example above are for an effective 2 body system, that of a tiny mass and a much much larger mass. When it comes to large masses effecting moons in orbit around other large masses, you g

Hi Hermione,
Yes indeed. And conversely the small mass object will make the big massed object move too, but only by a small amount.
Its a sobering thought, but each time we do a "slingshot manoeuvre" or to give it its proper name, a gravity assist manoeuvre, we not only alter the speed and trajectory of our spacecraft, but we alter the speed and trajectory of the planet or moon u
