A132:CSM. C-type,S-type, M-type. C is carbonaceous, 75% of known asteroids S - type is silicaceous and is about(these are really only estimates) 17% of the known number of asteroids and then M-type Metallic. Most of the reaming asteroids that they haven't found a name for. Terrohertz, they are types of planetisimal regardless of location in the Solar system so that answer is incorrect. The Families in questions contain members of all three types you mention. Q133: If a body orbiting the Sun reaches Aphelion and is travelling at 29km/s, will it be travelling faster or slower when it reaches Perihelion? A133: Aphelion. as bodies approach another body then the gravitations forces are stronger. Wrong answer, if you read the question I asked if it would be travelling faster or slower at perihelion.

Q133: If a body orbiting the Sun reaches Aphelion and is travelling at 29km/s, will it be travelling faster or slower when it reaches Perihelion? Regarding Venus, it is certainly tidal lock as computer models have shown the effect perfectly. Regarding a body stopping anf falling apart, it cannot. The Mass of the body will possess the same gravity whether it is in motion or stationary, spinning or not, it is only it's kinetic energy that would change as a result. As the gravity would remian, the body would remain and would thus not fall apart. This is akin to the old notion that if the Earth stopped spinning we would all fall off. Gravity is a product of MASS and proportional to the density of the body, the more mass a body has, the greater it's gravitational field will be, however if that same mass is reduced in volume to a smaller sphere, then it's gravitational field will grow proportionatley, ie: Reduce the volume by one half, but keep the mass the same, you will double the gravitational field density of the mass, and so forth.

93) Message boards : Number crunching : BOINC casuing BSOD's!! (Message 107547) Posted 4 May 2005 by Jim Franklin Post: Hi Mike (From Tooting), I have thought of that, but as I have four machines all linked I find it odd that such a virus would have an effect on only three of them, although this is something I have considered, and have carried out several checks to ensure I have no infections on any of my machines. To this end, I have actually installed two alternative Virus checkers and run them on each machine to see what they pickup, I know that different products are better at finding certain virii than others. I have not run the antivirus programs at the same time though as I am aware that this can, in itself, cause some odd and sometimes serious consequences. I have checked the MS database and found nothing that would point to any other culprit. I have emailed MS in order to see if they can provide any insight, although I won't hold my breath. What strikes me is that the crshes have all occured with the same message after the same series of events, namely the lack of seti connection, swiftly followed the deferring of connection for exactly 1 minute then followed by the TCPIP error that seemed to be the actual cause of the crash. The train of events doesn't need Sherlock Holmes to figure it out in my opinion (although I realise with computers such arrogance can be dangerous!) When it comes to hardware I am as good as anyone, having built several hundred machines over the last 25 years and as an Electrical Engineer I understand the basic priciples very well, however I have not had the time to get into the newer programming languages as I once did with machine code, DOS and BASIC, of course it would also be helpful if you got error messages along the lines of "BOINC.exe failed whilst doing XXXXX and caused a Fatal error resulting in Windows shutting down to protect the machines" It would be so much more useful that 0x000000000a or 0x002a8490e0 which means bugger all to 99.999999% of the human population.

94) Message boards : Number crunching : BOINC casuing BSOD's!! (Message 107519) Posted 4 May 2005 by Jim Franklin Post: OK, I have had a look through the logs of all three machines, and the vent logs of all three show the same error message. On this machine every m,essage for each crash is identical (apart from time) Type: System Error Source: BOINC.exe Category 102 Error code 00000000a, parameter1 0200a8a0, parameter2 00000002, parameter3 00000000, parameter4 804e8790 The system rebooted from a bugcheck. The Bugcheck was: 0x00000000a(0x0200a8a0, 0x00000002, 0x00000000, 0x804e8790) A dump was saved in G:\Windows\memeory.dmp Both the Dell and the laptop have the same errors except for the location of the saved dumps being on their C drives respectively. The interesting this is that on all machines just before these crashes BOINC reports that it cannot connect to Berkeley and there is a TCPIP error but the error log contains no information as to what this error was. On the Dell one crash occured in this sequence: 07:34:26 Shedular RPC to http://setiathome.ssl.berkeley.edu/sah_cgi/cgi failed 07:34:26 No Schedulars Responded 07:34:26 Deferring communication with project for 1 minute and 0 seconds 07:35:26 BOINC.exe error (As above) 07:35:26 TCPIP error 07:35:39 System Reboot error message I chose this from the Dell simply because it ONLY runs BOINC, literally nothing else, and so this was a good indicator, I then checked the timestamps for the other two machines and they occur in exactly the same fashion. The really interesting thing is that the crash seems to occur after a communication failure with Berkeley which is poceeded by an exact 1 minute 0 second lay off on all three machines, this then creates this TCPIP error that causes the reboot or the BSOD. I have checked every BSOD and crash on all three machines, the time lay off is ALWAYS exactly 1 minute and 0 seconds? There is no doubt in my mind that this is something minor in BOINC that only occurs under given circumstances when the client cannot communicate and it is deferred for 1 minute. Anyone got any thoughts on this?

96) Message boards : SETI@home Science : Humans as Aliens? (Message 107150) Posted 3 May 2005 by Jim Franklin Post: Murasaki, I know that some feeble minded researchers attempted to paint the "Hobits" as suffering from Microcephaly, but this load of old tosh has been soundly and squarely blown out of the water with concrete research. Also, Microcephaly always results in a reduced Cranium, they are not normal sized craniums with small brains, the Cranium and Brain are proportaional in size, also those suffering from Microcephaly have severally reduced Brain functions, learning disorders and extremely reduced IQ in most cases. Evidence from Flores shows that the "Hobits" suffered none of these traits, and the fact that the Fossil skeletal remains found so far stretch across a period of time dating from 90,000 years ago to only 13,000 years ago means that these poeple were very common. The statistical odds of finding these skeletons is staggering, the odds that the only ones found also happened to be the extremely rare one who had suffered from Microcephaly, something that only effects something like one in 10 million humans are so staggering that is is safe to say impossible. The Hobit's ARE a new species of the Homo branch of Primates.

(Message 106818) Posted 3 May 2005 by Jim Franklin Post: I ran a Farm of 53 machines at one time for SETI Classic, power was an Issue initially as my main switch was a Time delay 100mA RCD, this thing was going to trip as soon as I started to build my Farm, so I removed it for a simple DP Isolator, put Kitchen and external socket, plus garage supplies on RCBO's and then ran five 20A 4mm Radial circuits up to the spare room in order to power the Farm. These were protected by Type C 20A MCB's to avoid any nuisance tripping issues. A/C for the room was provided by a converted Freezer in the Garage and some 100mm Aluminium flexi ducting, this was finished off in the room by 100mm plastic flexi ducting. The A/C was needed as the temperature in Barnet during the summer of 2003 rose to over 40C on several days and hovered around the 36C mark for several weeks.

There are no Virii, trojans or aother nasties on my machines, they are checked regulaly with decent software and this is not an issue. I have alweays stopped BOINC before running scans every few days so it is not that the Software and BOINC cause the lock-ups and BSODs I have posted this message on other boards and got feedback that it does occur on other systems, it may not be common, but regular enough for other to notice. I have been running SETI since 1999, I have over 30K classic units to my name and have run up to 50 machines (self-built) so I know who to identify any potential conflicts and problems with them. What concerns me is that the Dell ONLY RUNS XP Pro SP2, BOINC and Trend AntiVirus (Which only runs when I tell it), there are no other drivers loaded except the motherboard ones, yet is has the same problem as the laptop and this machine. There is an old saying in England, "If it walks like a duck, looks like a duck and quacks like a duck, then it is assuredly a duck" BOINC is the cause of that I have no doubt, it is simply a case of finding the cause within BOINC, is the background software that is the issue, or is it solely related to how BOINC interacts with the SETI cleint and work units?

99) Message boards : SETI@home Science : Humans as Aliens? (Message 106814) Posted 3 May 2005 by Jim Franklin Post: Riley, I think some of what you said is spot on, in the early stages of any society environmental factors have to be a profound influence on the progress and direction that society take. As fr the linear progress of Man, well that is simply laughbale, nature doesn't do much in a linear manner, and evolution is nothing like linear as there are simply too many factors involved for it to be. The simple fact is that Humans have been "Intelligent" for about 1 million years, Homo Erectus may not have been able to build cars, but these were far from stupid creature, I find it laughable when so called "Intelligent" researchers speak of Erectus being a smart chimp or something of this nature, or they attribute no vocal skills to the creature. My mothers cats speak to each other, as do wild Lions, Chimps and other Primates, how dumb of us to think our ancestors could not vocalise, like it is something that only humans can do. Research is showing that Erectus was a lot smarter that has ever been given credit, that they knew how to make boats and cross bodies of water over 800,000 years ago, 10 times further back than previously thought. The diminutive Homo Floresiensis found barely 18 months ago shows us that even with a brain of reduced size, the thought process of these miniture Homo Erectus was a lot more sophisticated and advanced than anyone thought possible. Who knows what Erectus may have achieved prior to the emergence of Homo Sapiens some 300,000 years ago, the fossil record is woefully incomplete, especially for Human evolution, recently I read that only one skeleton in 250,000 is ever fossilised, and only one in 1000 of these will remain complete over geological periods, so the simple truth is we know less than nothing about our ancesters. Our species is an inquisitive, semi social territorial predatory omnivore, there is no reason for us to think that our behaviour now is any different to that of our ancesters some 200,000 years ago. We are not any smarter, so the real question is "Why did we suddenly all develope societies and emergent technology around the globe at the same time" This is too coincidental if you ask me, there had to be some other influence taking place, I do not favour ETI interference as some may claim, but I do favour that perhaps a group of Humans had developed further than others and they spread this "culture" around the globe over a period of several hundred years. This is not that far fetched, it is EXACTLY what European did from 1450AD to the modern era. Had this occured say 40,000 years ago, prior to the Ice age, who is to say what level of sophistication this society may have had, what technology they may have developed, the Ice age would have removed all traces of it, and had they understood engineering as we do, then perhaps their buildings were not over engineered like the old ones which have survived for thousands of years, but perhaps they were engineered Just so, and nature had removed them from the landscape? There are most certainly serious anomolies with Human development, and whilst I am not convinced that what i have proposed as a possibility actuially occured as I have said it, there is no reason for us to believe it did not either. Perhaps the Ark of myth and legend was not a wooden sailing ship, but a generation ship to take survivors and other creatures to another world, perhaps the Two by Two was frozen Foetus of creatures here that could be allowed to thaw and develope naturally on the new world. We know that the Ark could not have been a wooden ship as desribed on Earth. Maybe Battlestar Galactica is partly true, and our ancestors left what they thought to be a dieing planet for a new home, and they have not returned. Some survived the Ice ages and they founded the societies we see in the historical record. I do not believe Humans are Aliens in as much as we came here from elswhere, the actual scientific evidence for our evolution on this planet is too overwhelming, but it is possible that we are the Alien somewhere else, regardless of how improbable this may be. We will be one day that we can be confident of, and if we have done it once.....
