matrices can be helpful if you got an equilibrium going on between a lot of products. they can help you to calculate the concentrations you'll get in the output stream

theres a buddy list? what? holy crap! you wonder how you can miss these things for so long. i don't intend to use it though.

i want that shirt

it would be swap. its kind of pointless. you can do it on vista (its one of it supposed 'new' features) and you can do it on linux(you can even use a floppy drive for it and have been able to do it since it could handle swap partitions) but i don't know about XP. you will already have a swap file on your harddrive so it isn't going to do much.

okay, you need a bucket for the water and a hungry frenchman for the snail. if it fills up without rain your screwed if it doesn't your sorted but you have a frenchman hanging around.

looks like a shrunken version of my neighbours pond. without the fish as well i hope. if it rises on its own then there is something fishy going on, if it only rises with rain then its just poor drainage in the soil at that part of the garden. the 'green crap' is pond scum.

it does sound like he means earth. in that case, no. there would be evidence of such a temperature rise (like thinner polar ice caps for one).

right, now we can get somewhere. for the first part, you can consider the oil to be made up of little tiny strings. consider you had a bucket of long strings and a bucket or short strings. which would be the easiest to move your hand through? the third part is basically the same as the first part. and for the second part, its not going to get much simpler that the question given.

well, what does he need to know about the droplets? is it milikens oil drop experiment? surface tension? what?

so was it the sun that was 50-100*C hotter or the earth? i have a feeling you mean the latter.

this is a pretty simple phenomenon. the air in your lungs is saturated with water vapour. when you force air into your mouth and it gets compressed, it can hold slightly more water vapour. so some of the spit in your mouth evapourates(a really tiny amount). when you release the air, the pressure drops and the air can no longer hold all the water vapour so it condenses out. this isn't steam, as steam is perfectly transparent but little tiny dropplets of water. a similar effect is seen when planes depressurize suddenly at altitude. the cabin will become foggy as excess water vapour condenses out from the sudden pressure change.

not only that but the turbines produce very very hot exhaust. i watched a documentary about a gas turbine motorbike and they had stopped at lights and the car behind started melting where it was plastic and rubber. the guy in the car kept edging forward for a better look. you also have to consider that a turbine takes a lot of fuel to get it started. this is fine for trains travelling a few hundred kilometers and up but for a car running down to the shops and back its not going to be very efficient. it would probably waste more fuel.

well, they have a much higher power to weight ratio so they can accelerate a car of the same mass faster. they also have a relatively flat torque to RPM line so they offer nearly the same torque from stationary to the top speed. to go faster than the tesla does they will still need a gearbox as the engines still have a rotational speed limit although it is much much higher than an IC

there is no absolute frame of reference. the only measurements possible are relative measures. thats the whole point of relativity.

yeah, batteries at the moment take a while to recharge. Fuel cells can deliver the power and be refilled as quickly (or even quicker) than a petrol tank but we've got to tweak it a bit for viable safe storage of the hydrogen(or methanol depending on the fuelcell). Supercapacitors can be charged very quickly if you use a special high voltage socket but they lack the energy density to be practical at the moment.

no, my hayfever doesn't kick in till late may through to early august. i won't be sneezing much until then.

as a hayfever sufferer i can definitively say that slapping your thigh(or any other part of your body) does NOT stop a sneeze.

ahh rocketmans thinking laterally, literally.

well thats simple, you label the northbridge as the tracking module and the tracking module as the northbridge. if they remove what they think is the tracking module it won't work.

and, when older bridges were constructed, say in the late 1600's, do you think that they were considering heavy goods vehicles?

the article said it was one of the magnets on the accelerator tunnel not the detector. although, both are pretty big and could blow up if you made them wrong.

its real. high performance electric motors have existed for decades. its only now that we've managed to produce batteries and supercapacitors that are capable of supplying the power for long enough and in a small enough package to be used in a car. A 248hp electric motor is nothing special, or that big come to think of it. it's smaller than an equivalent powered piston engine. lighter too.

i know they were hoping to create mini big bangs but thats just ridiculous

there are other ways to reduce weight than removing the advantages of retractable undercarriage systems. one example is, don't paint them. this reduces the weight by quite a bit. you can always look at using lighter fluids in the hydraulics. ways of making the various alloy lighter. using a wireless control system would cut out the need for a LOT of cabling in the aircraft. this can all be done now and doesn't add the complexities of training pilots to land on a platform that they can't even see. also, how would this hold up in foul weather, planes move around a lot then. and emergency landings suddenly become a lot more dangerous. and as capn said, they would need to be able to be used on everything from a cessna to the A380. not an easy thing to do.

that fact that we have only found one rocky planet so far doesn't surprise me. They are tiny compared to gas giants and we can only just about detect the gas giants. and even that depends on us looking at the system edge on almost.
