  1. Perhaps YOU can explain how a specific tree can be a reliable indicator of temperature change one year, then cease to be the next. Sorry - if you have to falsify data so that the result fits the hypothesis, then you're doing science, you're doing fraud. Defend it all you want - it's still fraud. well, you could cut the tree down
  2. Because there is a known problem with the data set 1960-present and people that did the original research recommend not using it because it doesn't agree with the actual temperature data available and they haven't figured out why yet? That including the data would lead to a spurious decrease in the data which is clearly not correct? All data has limitations, and correcting for them and substituting higher quality data when available and scientifically justified is not fraud. IF your altimeter stuck at 5K would you go in waiting for it to change, or use an alternate method?
  3. UCLA does NOT offer a major at either the undergraduate or graduate level in Thermodynamics, nor in Heat & Mass Transfer. It is fortunate they don't, if this is supposed to be a graduate. He is apparently confusing heat capacity with infrared absorptivity. For a given change in temperature approximately 0.25% of the change in heat content of the atmosphere would be due to the change in heat content of the carbon dioxide in the atmosphere, but that is irrelevant. The issue is how much outgoing radiation it will trap, and that is around 9-26% of the total. It is like arguing that fiberglass won't insulate a house, since its heat content is only a fraction of the heat content of the whole house.
  4. For a more nuanced discussion I would suggest www.realclimate.org. Like the original Watergate break-in, I suspect this will be far more interesting for who did the breaking than what was stolen. I don't think it is just a coincidence that this happens just before the Copenhagen climate conference.
  5. I knew it was a mistake to keep the details of the conspiracy on an academic mail server, but Al Gore said the secure system in the batcave wasn't ready yet. Looks to me like a bunch of academics dealing with end effects in smoothed data series, reviewing papers, and dealing with abusive freedom of information act requests. Also, i wouldn't necessarily believe everything I read off of a Russian FTP server.
  6. He wasn't stealing the ferret, he was training http://en.wikipedia.org/wiki/Ferret_legging
  7. $79 million. Seems expensive until you realize that it would somewhere in around 10,000 to ship a liter of Perrier up there, and finding a source of water that is accessible would open up a lot of possibilities.
  8. First off, this is an art project, not a science project. three possibilities suggest themselves: 1) purchase a styrofoam ball, label it nucleus, explain that at this scale, the 1S shell is somwhere around Saturn 2) turn in an empty box, explain that you built it HO scale 3) turn in the styrofoam ball, explain that it is the 1S orbital vanadium in it's +21 oxidation state
  9. We used to use etched tungsten wire to make tips for a scanning tunneling microscope (these can image individual atoms under the right conditions). I've had those stuck nearly an inch into my hand and never felt a thing because the tip was so sharp.
  10. Um.... FDA currently allows irradiation of meat and vegetables. They just require that the food be labelled as irradiated. Irradiation does nothing about botulinum toxin that is already in the food. Nor does it do anything about contamination that occurs during preparation or shipment.
  11. from the editorial describing the article: That must be one heck of an article. Unfortunately I can't find it on Lindtzen's publication list to review the original source. The assuming the summary accurately reflects the publication, it does raise a few questions : 1) Graph C shows a comparison of the ERBE data to 11 climate models; the IPCC data website shows 23 models ... how does the data agree with the other 12? 2) of the 11 models that show a negative slope between the , only 5 of them show a correlation I would even consider putting in a publication of these 5 two sets of data are just different resolution runs of the same model, so call it 4 out of 11 3) data presented in the summary show a change SST of about 1.2C, but they claim from graph D that there is no change SST; perhaps the author is picking a subset of the ERBE global data I hope they are taking a consistent subset of the computer model data 4) they implicit assumption seems to be that all of the long wave radiation is from the sea surface temperature change, but one of the observations of ERBE experiment is that clouds that form over the ocean reflect more long wave radiation than clouds that form over land, so the observed flux may be combination of long wave radiation from the sea surface and reflection from the sun 5) the statement in the summary "Less infra-red heat radiation going out into space should correlate to cooler sea surface temperatures, as there is less heat available to radiate out. More heat radiating out appears when sea surface temperature increases have occurred and more heat is available to radiate." is only correct if everything else is held constant and there is nothing absorbing the longwave radiation like, ah, CO2
  12. They use solid sodium instead, which we all know is perfectly safe for kids. I'm also curious what this does to the internal resistance of the battery (not helpful when you need lots of current fast). This may present some minor marketing difficulties. They have made an improvement on an interesting but not very practical battery technology. I'm not sure that the high energy density is all of that big a selling feature for home use in PV systems. People seem willing to live with lead acid batteries, they just want lower cost and longer life.
  13. Not sure where the original quote came from so I'll reply here. Any electron microscope (except the most basic student models) is equipped with detector(s) to do elemental analysis on a sample using the x-rays emitted from the sample when it is hit with electrons. It doesn't work so well for light elements, but for metals it is an ideal tool for the job. You can tell if a particular spot in the image has barium in it or do an overlay that shows what parts of the material contain barium. I don't agree with the conclusions, but they seem to have used the right tool.
  14. Given their yields so far, maybe we should cite them for setting off fireworks without a permit.
  15. Sorry to hear you have to sell. There is a huge gun show in the Harrisburg farm show building this weekend (Mar 21). Pay the admission and ust walk the aisles with a for sale sign on the gun. You'll get offers from the dealers at the tables and from other people walking around. PA allows person to person sales of long guns with no paperwork required.

    MAC Users

    When I was trying to make the same decision I talked to a mac developer and his opinion was that fusion was a better technical solution, but had just come out while Parallels had been out longer and had most of the bugs worked out. I have three programs I need windows for, and most of the time I just reboot into windows using Bootcamp. If you just have the one program and your work flow allows, Bootcamp might be a good alternative, especially if performance is important.
  17. Declare a 1 week bank holiday to figure out exactly where the bad debt is concentrated, then thin the herd. Sounds harsh, but this is the same industry that backed bankruptcy reform... don't want to see any deadbeats weaseling out of their obligations. For what it's worth, i doubt the effects on the credit markets will be as dire as predicted. The US financial industry may be in sad shape for a while, but there is still a lot of oil money out there looking for a decent return on investment. To stimulate the economy, how about a combination of public works projects to put money directly into the economy, at the lowest levels: 1) develop alternative sources of energy: wind, solar, some nuclear 2) infrastructure development... geared toward reducing reliance on individual cars : better light rail, bike lanes, higher density housing near work and shopping areas 3) spending on energy efficiency 4) CO2 mitigation: imagine the CFO of Lehman Brothers planting trees on a reforestation project for minimum wage We will still pay the price for spending that much, but the benefits will be distributed as broadly as possible, and we may just solve some long-term problems.
  18. In addition to the usual safety checks, pull out the packing card and make sure that the reserve is in date and, more importantly, of reasonable size. I once rented a rig, checked that the wing loading on the main was OK, then found myself under an F-111 7-cell reserve loaded at 1.2:1. Not outrageous, but kind of zippy at 34 jumps, especially since in the excitement following the cutaway, I forgot to do a practice flare.
  19. Looks like a paw-paw , but the shape seems too regular, might just be immature. Did it smell like a banana? http://en.wikipedia.org/wiki/Pawpaw
  20. I thought about this for a while, and I've come to the conclusion that it's nearly impossible to write a consistently great scifi series (series defined as trilogy or greater). For example: J.R.R. Tolkien, The Lord of the Rings: consistently great, but also not a series it is just published in three parts Larry Niven, Ringworld: Great but not consistent. Last book didn't just jump the shark, but actually rished it Frederick Pohl, Heechee Saga: The only thing wrong with the first book was that I had to read through the next two before I realize the magic wasn't coming back J.K. Rowling, Harry Potter series. Consistently good, but not actually great. William Gibson, Sprawl trilogy: he comes the closest. I'd give Mona Lisa Overdrive a great-, the other two books are fantastic William Gibson, Sprawl trilogy: Consistently good, but you'd never have heard of him if it wasn't for the Sprawl series Frank Herbert, Dune; Should have stopped at a trilogy, but those of us who stuck in there after God Emperor of Dune (all six) found it good up to the very end. I think the ending of Chapter House Dune might have been a set-up so his son would have a way to earn a living Frank Herbert, Destination Void series: should have stopped at a trilogy Frank Herbert, Bureau of Sabotage series: he should have gone for the trilogy Neal Stephenson, Baroque Cycle: heavier than any other series, that's for sure Stephen King, Gunslinger series: the first book is the best thing he has ever written. In the later books he didn't just beat the mule to death, but actually et the eyes. Sean McMullen, Greatwinter trilogy; it's rare to stumble in mid trilogy and recover, but he pulls it off. Give Miocene arrow a miss, but Souls in the Great Machine and Eyes of the Calculor are very good.
  21. I hear this all the time regarding falls/jumps into water. Take a pan of water and press your hand down onto it. It is barely noticeable. That's all the surface tension you are going to get; the water doesn't how fast you are going when you hit. You get hurt because you hit something dense and incompressible. People talk about breaking the surface tension. The surface tension does fluctuate on the level of water molecules, but on a timescale that matters to a diver, it is effectively always there, ready to go. Ironically, surface tension is at a maximum on freshly formed surface (for example where something just struck the waters surface or where a bubble has burst) and decreases as the oils, detergents and crap have a chance to diffuse to the surface. Airbubbles make it easier because they make the water less dense which lessens the impact a bit, and make it compressible, which helps a lot.
  22. four ears and STILL does not come when called
  23. ignoring the genetic make up and going with the skills: basic skills : everyone is from a rural area and grew up camping, hunting and fishing. In their adult years 5 of them took up adventure sports: white water rafting, extreme skiing, rock climbing, while the other five stayed home and sewed, brewed beer, cooked, etc. as far as professions: 1 dental hygenist 1 emt-w 1 amish farmer (lapsed) 1 with an AA degree in sociology, who audited a lot of philosophy courses 1 with an AS degree in Biology 1 crafter ... someone who know how to do a bit of knitting, pottery, glass blowing 1 who is 2 years into a materials engineering degree 1 with an AS degree in botany 1 flint knapper/primitive living skills instructor 1 with an AA degree in History, with an emphasis on Paleo-history My basic design philosophy for the group was to be able to survive long enough to domesticate some animals and make steel, while retaining the germ theory of disease and a vague knowledge that epicureans had something going philosophy-wise, and the national socialists didn't.
  24. EPU emergency power unit. Runs on engine bleed air or hydrazine to provide 10+ minutes of emergency power and hydraulic pressure. When hydrazine mode is triggered it makes the plane dangerous to approach after landing. The hydrazine is toxic, reactive flammable.
  25. Moon clips are for revolvers, not semi-autos. The Webly Fosbury is a semi-automatic revolver. Later models were chambered in 38ACP and used moon clips.
