Why does wet cold air feel so much colder than dry cold air?
insane_alien replied to CaptainPanic's topic in Physics
between 95% relative humidity and 20%. the temperature was 120*C (relatively it was very cold). pressure was 5 Bar. -
planets are nothing like trees jsispat, please don't post that it is.

Why does wet cold air feel so much colder than dry cold air?
insane_alien replied to CaptainPanic's topic in Physics
it is not psychology as a warm object in cold wet air will cool faster than a warm object in bone dry air (I have done experiments which show this even though we were looking at a different parameter). humans would percieve this as 'feeling colder'. -
Celestia will give you a good simulation of the solar system. as well as a lot of other ones that we have discovered.

Ozone, from your link/ blame disney. -
Simple multiple choice question about conventional current
insane_alien replied to scilearner's topic in Physics
all i can say about conventional current is: stupid US idiots. even after it was discovered that negativly charged electrons were the charge carriers they decided to keep the conventions from when they thought it was a positively charged charge carrier. while this is fine for most electronic circuits, it gets downright confusing for when you want to see what actually happens. -

yep, thats why hot muggy days feel like hot muggy days. says it all. -
plywood would be fine. it would be better to build it with very light materials but then add some ballast afterwards. this means you can adjust how heavy it is so you get a good balance betwen speed and control. and mainly because you don't want to test it and have it just sit there and not move. i'd recommend balsa wood for the frame. it is light and strong and easy to work with(i've built model bridges and planes out of it.)

Chernobyl - Dangerous, Exciting Holiday!?
insane_alien replied to Teddy_Csx's topic in Other Sciences
this was 2 years ago, he has either done it or thought better of it, either way he isn't around here anymore. -
40 strikes a year, be optimistic and call it 1GigaJoule a strike, 40GJ a year = 109.5 MJ a day = 1.27kW and thats probably taking in all lightning over a fair radius around the tower. according to wikipedia the average is half that. and not all conductors will be struck 40 times a year. probably works out to maybe about a milliwatt per square meter. hardly worth collecting unless the price of electricity skyrockets a fair bit.

when have experiments shown that V=mk? thats not reality. therefore your idea is not science. its not anything.
-
and when have you ever seen ink spontaneously start a fusion reaction.
-
all fine up to here. only if the ink is colder than the surroundings or absorbs a wavelength of electromagnetic energy incident upon it. it would be more apropriate to reffer to 'ink molecules' here as ink is not an element. yes, but not a lot of mass in this case. unless the atoms were already unstable then this is not going to happen. increased mass due to thermal energy does not break appart atoms. you are mixing nuclear bonding and chemical bonding here. the chances of DNA forming from ink that has just took the amount of energy required to fuse its atoms is NOT going to happen as the products will be in a rapidly expanding gas cloud. you do realise that this is thermodynamically impossible yeah? err en englais sil vous plait. what does this have to do with making things possible just by thinking them.

i think the missing mass discovery came after the supermassive blackhole discovery. so eh none.
-
they are not mutually exclusive. Supermassive blackholes at the center of galaxies is fact not hypothesis. IIRC we have yet to find a galaxy without one. Missing mass is also fact as this is observed. Dark matter is just used as a placeholder for whatever it is that makes up the extra mass. it may even turn out to not be matter.

A glass full of H2O and Na and Cl is What?
insane_alien replied to Catharsis's topic in Organic Chemistry
this combination covers around 2/3 of the earths surface. take a guess. -
Anyway, just because you can imagine something doesn't make you right and equally, just because can't imagine something doesn't make somebody else wrong. in short, what you imagine happens is irrelevant to science unless backed up by observation and experimentation.
-
technically, it is a rational number if you use base sqrt(2). cause then it would be 1.

yep its tetra methyl heptane and we seriously need a way to put in chemical structures on this forum, that already looks bad.(not the fault of Snail13579 though)

science is very open minded(we even want the established theories to be wrong to some degree as it will lead to a certain amount of glory to the discoverer of the new theory.) but we have a filter on our mind. This filter is called the scientific method. Its purpose and function is to discard all the illogical and false crap that tries to get in. what makes your theory better than other theories? It must explain EVERYTHING that the old theory it replaces does AND then something new. Newton, Gallileo, Einstein, Rutherford, Archimedes, all these scientists and more spent their lives experimenting and devising theories to explain them. They have libraries full of evidence that supports their case. what is your evidence so far: 'I'm excited' think science wins there. But tell you what, you start up another thread and CALMLY lay out the details of your hypothesis(it will not be called a theory till it has considerable evidence in it favour) and we will conduct a peer reveiw on them. IFF(yep, thats two f's, go look up a dictionary) it holds up then we will accept that you are onto something.

CD/DVD drives generate a fair bit of heat. you can test this for yourself be taking a disk out after its been used and feel how hot it can get. as your laptop already has thermal issues, it won't be helping the matter much.

Cancer expert says: don't wait for the science, panic now!
insane_alien replied to bascule's topic in The Lounge
this is the perfect time to be perfecting the 'two tins and a bit of string' communication method of old. -
the people who say science isn't creative should definitely take a deeper look at quantum mechanics and relativity.

Can Some of These Mysteries be Explained Logically?
insane_alien replied to jimmydasaint's topic in Speculations
Apparently there was also a theoretical landmass in the south that was supposed to 'balance out' the landmass in the north. so it was tradition to insert one on maps. this one shows hallmarks of just being filled in by a human than actually following a coast line on an expedition.
