  1. It means their product range. Type "Line up in photography" into google and see what it comes up with. All the hits I could be bothered to read were going on about their line up of cameras for the new season. i.e. their new product ranges.
  2. Nice one. That would work. I've heard of the problem before but I'd forgotten how to do it.
  3. I'd do it. The old saying "When in Rome...." If there are here in the UK then make them use our notation. It's much better anyway! Quite!
  4. I really hate the way that on the continant they use a comma as a decimal point. Really could confuse issues as we use a comma to tidy up large numbers to denote thousands. eg. 100.001 (one hundered point zero zero one) would be denoted as 100,001 (which to me reads as one hundered thousand and one).
  5. Thank you. I've found a university with HT-DSC/TGA. They will run samples alot cheaper than the industry quotes I got in. The pottery furnace is a good idea pioneer -thanks. I have added Al2O3.Si2O3 already. I will try MgO as well now - Thanks H4tt3n. I would like to own one of these HT DSC kits really - However the quotes I got were in the region of £40K... Maybe not then! lol.
  6. Sounds like he was into Chemical Physics. It's the crossover between Chemistry and Physics and encompasses a little of both. PS - I just looked him up and it says that he was a Chemist and a Physiscist.
  7. Machine Code!! Wow! My mate has programed directly machine code. He is a developer and game writes for consols. He used to write a column for one of the games mags in the 80's... 'Crash' I think. I've only ever the done the most basic things in BASIC. (Q-BASIC, VISUAL and perhaps another form). And even then I've had to get help..
  8. You get contacted by the secrete services to be recruited as a spy. You meet James Bond and everything!
  9. The old "Nylon Rope Trick" isn't a bad demo. You pour in your diamine thingy and add your sebacoyl chloride as a second layer - dip your rod in (phenar phenar) and pull out the rope from the interface between the two liquids as they polimerise. Can be difficault to get right and sometimes needs a little practice, but demonstrates polymerisation quite well. Nylon is something everyone knows about as well.
  10. What year are you in out of interest? If you are really interested they might have time to speak to you after class (if you can be bothered to stay behind that is?) I've got some equations in my old university physics book which might be of interest. I'll rake them out later. They might not be too different to Klaynos's one though. Strange things happen when you get close to the speed of light!! Space and time sort of 'warps' and 'distorts'. It's difficault to get your head around.
  11. MD - why don't you go and discuss it with your school teacher - they might be able to help you understand it.

    Egg

    I'd say it is - if it's fertalised - that is untill you boil it. It's nothing like the earth though. Are you mates with Jissplat?

    A Fun Thing

    I'm sure you've seen this, it's silly, but I think it's cute. As they pass the apex, the 6's become 9's and thus drag the wheel down on the right hand side - propelling the wheel to the left. [ATTACH]1838[/ATTACH]
  14. OK - When I spent some time at the Rutherford Appleton Lab in Didcot I used the SEM quite alot. This has an automatic Liquid Nitrogen feed which kept the machine cool. Every so often, when the level got low, it wiould automatically start pumping N2 through a pipe from the container next door to fill up the dewer built into the SEM. One morning, there was a new cleaner sent in to mop the floor of the clean rooms there. As she walked into the room containing the SEM the automatic N2 feed kicked in. It makes a hissing noise and you get a load of N2 venting out of the top of the SEM whilst this happens. She mistook the N2 gassing out of the machine for smoke and thought the machine had gone wrong and was going to explode! She ran out of the clean rooms screaming for help before someone worked out what she was on about claiming the SEM was 'on fire'. She was quite embarrased.. I love the stuff by the way - it's really nice to play with. Even just tipping it on the floor and watching it boil around is great!

    Birth of Earth

    Nor is the earth -- it's just rock.
  16. This is a problem I have at work. (not sure if this is posted in the right place- especially as it the amateur science thread but here goes). I have a glassy like substance which starts to sag and run at about 850 to 950C. Up until then it holds its shape pretty well. I have tried several additives to up its melting/sagging point. All work fine in my in house home built furnace which gets up to about 900C. When I send my samples off for larger scale tests the temps get up to over 1000C. I have tried and failed (well I have upped it, but not enough) in the past to mix additives which will up the sag point of this substance. We have some new ideas and want to test them out. Theory says these 'new' mixes will go above 1000C (1200C would be nice). The problem is my in house kit doesn't get hot enough and I can't really afford to send samples off for expensive full scale testing until I'm sure what I have done has had an effect on the sag Temp. So: Does anyone know of any kind of calorimetry (like DSC ot TGA) which will take temps up to 1250C or higher? I really need to buy, hire or have someone run some tests for us before continuing our work. Maybe a I need to build or buy a better furnace? Thanks, P. UPDATED through further searching: I don't suppose anyone has access to High Temperature DSC equipment do they? I caould send you a couple of samples through the post to put through. The new HTDSC's apparently get up to 2000C.

    Birth of Earth

    Really now! I wouldn't call these dead as such because they were never alive, but: A frozen lake. A Geode rock. A bubble. A dried up sea bed or a crusted over muddy puddle. The earth.

    speed of light

    It's where time dilation comes into it yes? The space ship actually moves slower in the stationary observer's reference frame? Which is why if the observer and the ship's captain are twins, one will age faster than the other because his time has passed differently for him.

    speed of light

    Thanks - that's exactly what I thought.

    speed of light

    Escuse my complete ignorance here please guys but I have a couple of questions. 1) I thought things couldn't go faster than light? 2) If a space ship flying past an outside stationary observer in space was going at ...lets say 0.5C and turned on the headlights. What is the relative speed of the light beam from the head lights compared to A) the Space ship and B) the stationary observer? I could probably look this up but from some of the reading I have done I am getting a bit confused - It was years ago when I done this. Thanks.
  21. I actually think she's alright! I never said I was Judging them either way - I just said we should just let them get on with it without wasting important police resorces etc.. Oh and I love Miles Davis, Jimmy Hendrix, the beatles andloads of others who were obviously under the influence. ( I was about to play advocate and say who knows what they could have acheived without the negative impact of drug taking on their lives... but who am I kidding eh? ) I just think they could be abit more responsible and low key about their drug taking - some give it a bad name. But if the photo was from weeks ago and the drug is untraceable - they were talking about convictions on photographic evidence alone - No Way!.
  22. As I said - let's let natural Selection take it's cause then. Let them do what they want as long as they don't harm anyone else. With all the hype and media attention it glamourises it further. Just put a quick ulogy in the local paper "whinehouse dead on OD" and say no more about it. BUT people will go on and on and sensationalise it all so that kids will attracted to the hype, get interested and start to sympathise and copy. Anyway - who cares! Shame to hear that a much liked guy has gone. I didn't know who George Carlin was, but from the things I've just read he was cool.
  23. There was a thread on this a while ago - I don't know if this helps? http://www.scienceforums.net/forum/showthread.php?t=32327&highlight=hole+earth
