Other Sciences

You guys did a fantastic job in answering my last question, so I did't hesitate to ask another one here. Which metal is harder? Platinum or White Gold I know that white gold is coated with Rhodium once a year, is Rhodium stronger than Platinum? Thanks in advance!

If anybody know's Isaac Asimov's 10 Most Important Scientists in History and wouldnt mind telling me it would be a great help thanks schall_85@hotmail.com

Everyone up north watch for the aurora shows! Supposedly some tonight, tomorrow, and friday.

a recent contact explained that it is possible to create a "radon gun"using the radioactive components of a fire alarm, and i know that the government monitor the sale of fire alarms, anyone got instructions on the creation or more info about this?it is a general interest, i dont plan to create one, radioactive material is generally avoided by me

For a project I'm working on I need a rigid verbal definition of "what is real?". This is what I've come up with: Components of Existence influence one another in an observable manner. Can anyone refute this? In any context (science, religion, meta-physics, magic, etc.)? Is my logic faulty or perhaps inadequate? All comments will be greatly appreciated.

Why do higher levels of emotion result in flooding tear ducts? Also, aren't tears pretty much unique to humans? Probably an answer i could have found on google, but you know what, i like interaction and conversation better.

ive been reading the warning section on this site, does this mean discussing reflexology, homeopathic medicine and other methods of natural healing, that conventional science doesnt understand?is this neo facist darwinism accepted because there are some things we cant fully comprehend?

I read in popular science magazine that in some languages the colour blue is often represented by the same word that defines green, or darkness, in several languages. The suggestion was that some cultures haven't had a seperate concept of the colour blue. It is supposedly common amongst tropical people, where blue-yellow colour blindness is also sometimes more prevalent. There was also an experiment outlined which tested the effect of degradation of vision due to UV-B light, as a possible cause. Just seemed to me interesting anyway, and I was wondering if anyone had heard of this sort of 'cultural colour blindness' before.

Do you think the humanities are important to science? Personally, I'd say that they are important to sciences that deal with people. For medicine, I think the humanities are crucial. It is important that physicians learn how to connect with humans in a very real sense, and have a greater understanding of the human phenomenon. Many US medical schools are starting to add literature and art to the rigid core science schedule of first and second year medical students. Do you believe the humanities are important to all sciences?

A comment I previously posted on another thread : Oh so your idea is like mine, only more indepth. I think this idea is just as credible as the big bang. The universe suddenly expands into everything/ the particle suddenly begins to move thus simulating everything. Whats up with the big bang anyway, what triggered it? obviously this cant be answered, but then why do they claim that the big bang is the most reasonable idea? Its really not. Oh well i dont really care to be honost. Hey why don't you get the idea published? I wonder if it has already . . . . i'm going to go look. To see what i'm replying to, its A New Look at the Big Bang (a thread by Aman). I'…

Why do dogs bark at things we cant see? I know most of you don't believe in invisible manifestations of deceased living things, so whats the explanation though. Really the reason i started this thread was to just ask about the dog thing (my dog was just barking at one when i took her outside to pee), but while i'm at it i'll ask some ghost questions. Of coarse theres plenty of discovery channel specials on electromagnetism found in haunted houses, and light orbs that only appear on special cameras and such--- what do you think about it? The dogs see something--- animals are the first to detect earthquakes and similar phenomenon (even before seismographs?), maybe its not g…

We have no resonsibility for the past? What do you think about this topic?

What if our entire universe is made of one particle : moving so quickly that nothing is quick enough to detect when the particle is not there (because it hits that place so frequently there is no time to miss it)------ wait i guess that wouldn't work, because everything being made of the particle (in different positions) is made of that particle, and i dont think there is any way for it to collide with itself if it is the only thing in existence----- so say there are TWO particles.

Sitting here testing a old box of assorted bulbs, I came across a 6V 12.5W halogen bulb, when I tested it, I could feel the heat from it! So I thought I`de have a play I fitted into the reflective cone from an old flashlight and then tried it, made a good beam, so I used an old lens from a photo copier I stripped down many years ago to try focus the beam, IT DID! and started to burn bench within a fraction of a second, smoke and now a little black dot. It has a focal length of about 4 inches, I`ve glued it all together, and commenced experimentation It`ll light a cigarette, set fire to news paper THROUGH a sheet of glass, and boil a pencil lead in a test tube of …

in my efforts to make the perfect plant food for my Chili bushes, I was in need of some Phosphate (I have no Phosphoric acid left in the lab and was fresh out of Coke Cola to extract it from too) so I though I`de make some I had several boxes of safety matches in the lab drawer, so I decided to peel as thin as I could the 1`st layer of paper off the cardboard match box that contained the red Phosphorous. I put it in a test tube and heated it over a blow torch (bunsen burner), with my thumb gently over the end of the tube, all went well apprt from paper)wood) distilates inside the tube, but all chared nicely, freeing the phosphorous. when I took my thumb off the end o…

For matter to be three dimensional, would not every particle of it also be three dimensional? So wouldn't there ALWAYS be something smaller? If it is three dimensional, it has a depth in all directions, so it can be broken into smaller pieces (which can be broken intosmaller pieces, and its peices peieces and all following that order, must be made of something smaller (if it is 3 dimensional)). So what if there is a particle (its precises function of frequency or occurance per atom is irrelevant, as it cant be found anyway)----- it explodes from an infintismally (infintisimally dense with infinite smaller particles) small point, then collapses back to that point, and rep…

Do molecules in a solid object move? I thought that molecules in a solid object still move, but very slowly, only to stop once freezed. Then I read this "A secondary characteristic of a solid is that no matter how hard it is squeezed or pulled, the molecules do not move closer together or further apart." Is this true? And could you possibly attach proof for the correct answer? Thanks in advance!

I'm curious if anyone can direct me towards information regarding earthquake detection. What I primarily wish to know is if an earthquake occurs on one side of the globe, does it register on the opposite side? And if so, how?

Okay, now heres the catch. Does anyone of you know of anything such as "special paper" so that when you burn it, the ashes rise up? my science teacher did that today.. pretty impressive! we were SURE that it was no hoax with no strings attached etc. Very interesting.. just wondering because its been bothering me... (by the way.. im not like a expert in science but maybe it SOMEHOW was made in a way that the smoke carried the ashes up? i dont know... but it was in a classroom, about standard size, the celing was around 8 feet... and the ashes floated up then slowly drifted down again. Sorry for the long post. I would be VERY happy if you guys could answer. If you don't k…

http://www.scifuture.com will provide info on the future of modern science and technology. They expect to be up in mid 2004 but they have a splash page up and running.

the onset of what seems to be a head cold started last night, sore throat, blocked sinusses, head ache etc... I took some paracetamol and a Vit C 1000mg and hoped for the best. then I remebered hearing a Scientist say that Vit C has no effect at all on the common cold or Flu? two questions here: 1) why is it we can have Flu shots and they work and yet there`s nothing for the common cold? 2) does anyone have any tried and tested old or new recipe`s to either cure or help with the really irritating symptoms of a cold or flu? and is there any Science behind these ideas such as Chicken soup with plenty garlic and black pepper (other than it`s really yummy an…

We owe all our prosperity to science, what do you think about this topic?

As regarding sealed electric (21 turn) motors ... How can I increase the strength of the magnet and thus power of the motor?

we are planning to make a solar-powered module car. yet we don't quite undeerstand it works. one big problem is how to connect the solar cell to the engine. plzz heelp us Thanks any ideaz will help

I did it with my microwave. its leet. First, I got the frequency of the microwave from the data label inside: f=2.45Ghz We know that :nu: = f:lclambda: So all we need to be able to find the :nu: of microwaves is the wavelength. For this, I spread marshmellows out on a rubber plate. Then, I removed the tray in the microwave (so that the plate doesn't spin). When the marshmellows melt, you can see a distinct wave pattern in the melting. Measuring the distance between melted and unmelted marshmellows will yield our wavelength (actually, half of the wavelength). I measured 2.4 inches as the distance. Converted to meters thats .06096m. Since thats h…
