When I started to read the article, I was thinking to my self "Who cares?!?!?!" But as I continued, this article kind of answered my questioning for having a clock that acurate, besides the "No, it really is 12:43.35PM coolness factor"
Does anyone know any other good uses for such and exact timing system?
is this possible? i bought a wireless router a while back, but the location of my wired router wasnt the best (on the porch, a floor away) so i wanted to keep it and use the wireless one in my room (i bought it because it was cheaper than an AP) i could not get it to work i gave up then because it was a pain, and because its range was terrible
is it possible to chain NATs? and how would you do it??
Half Lives: U-235 = 7.037 x 10^8 years U-238 = 4.468 x 10^9 years U-239 = 23.47 minutes Th-90 (from U-234) = 7.5 x 10^4 years Ra-88 (from above) = 1.6 x 10^3 years
We just went over this in Physics, so I will give it a shot..
you dont start out with Pure U-235, only about 4%, (they get the percentage this high be making a Uranium gas, puting it in a large column, and skimming the lighter U-235 off the top)
So, they still have lots of other stuff, including other types of Uranium. (only 9.7% of natural Uranium is U-235)
only the U-235 is broken down by the neutrons that the current moderator, water, creating other radioactive elements such as Ba-141 and Kr-92 plus 3 more neutrons, or Xe-140 and Sr-94 plus 2 neutrons.
There is still alot of Uranium in the fission fuel, just not the right kind
(the "235" in U-235 represents its atomic weight, all Uranium has 92 protons in its nucleus)
(you subtract 92 from 235 to find the number of Neutrons in a U-235 atom)
(in order to get Plutonium, you start with U-238, add a neutron going the right speed, then you get U-239*[*=excited], which then beta decays, making a beta particle, a Np-239* and a neutrino. The Np-239* then beta decays and you get Pu-239, a beta particle and a neutrino. This is called "breeding" and is how nuclear bomb fuel is created)
WE have a Panasonic hard drive editor @ school, and it has a 17 gig hard drive, and it advertises as a "1 hour" recording device, so i am guessing that a single 60 minute DV tape is the equivilent of 17 gigs
is it possible to use a DV tape to store data, instead of digital footage, because that is a really cheap substitute if you can
My high school offers CCNA for the juniors and seniors, as a 2 year course.
different from many courses that i have read about on slashdot, we arent just learning to take a test. We spend a better part of our time on the routers and switched (we have one router per person in my 10 person class) wether its doing the exercises, or troubleshooting (3 of our routers (2501's) lose all memory when they are reloaded/turned off) (we finally gave up and have a router config in a text file on each desktop)
well, anyway, our highschool class is a class to learn the information, not to take the test.
I was about to go off about a dual color LED being more expensive than 2 single colored ones, but i went to Radioshack.com and realized that their R/G is 1.19, and the cheapest single color is.99, so, i didnt go off.
But, what if the red burns out and the green is still good, (red is hotter or more energy or something)(i dont know which, but im sure they are different somehow), then u are screw, and im willing to bet that this new multi color EL material is more expensive then 2 single color EL's
I have also been to both, the Incinerator in York PA, and TMI
I agree that while TMI has a cool factor, the incinerator was much more interesting, with the tour going to the tipping floow (where all the trash is dumped before the crane puts it in the burner) and a control room, with temperatures of the burners and everything
TMI's tour included going inside one of the closed cooling towers and looking @ the operational ones. most of the tour took place @ a tour center not even on the island, and there wasnt really any "wow look @ that" stuff to it, being as they cant really show us anything, and there's not that much to see anyway
I know what you mean, the other day, after the Stealth Force Beta article, I was looking at books about college and college pranks on Amazon, which is when I first saw the first item under the "Customers who wear clothes" section was clean underwear. Yes, the above situation is humorous, but I thought that the association of college and needing clean underwear was/is funny/funnier
Recently, the New Amazon Patents on Content Personalization article talked about how Amazon is patenting? its ability to combine items that is has no idea about, maybe with psychic powers?
After 9/11 everyone around here was very scared, because just like everyone know about Chernobyl in Russia, foreigners probably know about TMI.
This would not be an issue with a Fusion reactor, because what are they gonna do? Release Heluim into the air and make us all talk funny? Gee im scared
But the most compelling promise of fusion is in the fuel itself: fusion is produced from an isotope of hydrogen called deuterium, which exists in the Earth's oceans in sufficient abundance to supply the planet's energy needs for hundreds of millions of years - until long after the Sun itself has flamed out.
just to let you know
I do think that we will get fusion to work before we get cold fusion to be feasible
I thought that @ first as well, but it doesnt stand for "computer Aided Design" it stands for "Computer Aided Dispatching"
And thus, after re-reading, i determined they work for the 911 people or something like that, and they record what the police officer is saying over the radio
For instance:
Cop:they are shooting @ us
Cop:the passenger jumped out of the car!
the data is in order and timestamped
I know its not what we wanna talk about, but what about Micro$oft Messenger? I know I dont use it, but someone probably does, and I dont think that micro$oft will like aol doing this
yes, i know all about the finger user and talk user commands, but microsoft has power, wether we like it or not, and might be useful in this situation?
I am a senior in High School, and am still smarter than much of my class and probably had/have some kind of ADHD
At my school, we have a program, called "seminar", that takes the gifted kids out of class once a week and gets them together with the other gifted kids for some stimuli. We did a lot of trivia, logic puzzles and problems, as well as research papers on things that we found interesting. Just having a chance to have an outlet like that really helped me, I know that myself and several of the other seminar students looked forward to going each week.
Before I was enrolled in the gifted program, I spent much of the school day reading a book while the other kids did whatever the teacher was currently talking about. She knew that I wasnt paying attention, but she also knew that I didnt need to pay attention. The gifted program didnt make a difference during my normal classes, but it was great a building confidence and relationships with students that I could relate to.
I believe that schools are required to have some degree of "gifted" program in my area, but I have no idea what other schools offer.
Even if it is not the perfect solution all the time, having the outlet for our "smarts", even weekly made a big difference in how I thought of school and it being a waste of my time. Games played a big part in the logic and math exercises that we did, from spatial abilites in "traffic Jam" to math thinking in a card game involving several numbers that we had to +/-/*/divide to get the answer card's number.
A Part time outlet may not be the solution that you are looking for, but I know that it did make a big difference for me
But I bet there are also many people that have been to these countries that have not had their stuff stolen
and you act like its only a problem in the poor countries. Try any big city, there is petty crime run amuck.
try France, Spain, the US, etc, all of these places have crime, it is just the idea that it is sooooo much worse in these countries that stop people from visiting them
I havent researched this much, but i did spend about an hour reading several different sites related to this
I wasnt sure what "Tunguska" was or meant, so....
well, anyway, I was more convinced of the Antimatter posibility than anything else
where there was a given amount of antimatter in a field of some sort (plasma/magnetic/etc) and when it came into contact with the earth's more dense atmoshpere, the field was destroyed, bringing the antimatter into contact with regular ol' matter,
KABOOM
besides, the calculations i have heard about say that the object exploded some distance about the earth, which, yes, could have happened if there was fusion of hydrogen, but, the other effects of the Tunguska situation do not seem to go along with the comet theory
(thats just the.02$US of a non-whatever i would need to study to know about this stuff)
I think that all of this research is harmful, and that's without even bringing the "don't play god argument"
If everyone lived forever, and continued to have children, we would overpopulate the earth and starve.
Hunting season? its for the good of the deer and such, if we didnt keep the populations down, they would use all of their resources, and starve.
If we could double the lifetime of humans, than twice the resources would be in use, because just because you live longer doesnt mean you arent gonna have any children, you will probably want to have more of them
sure it would be nice not the have to deal with grandma dying, but we should worry about feeding the mouths we already have before we worry about making those mouths live forever

Just ask the Russians about how good it burns as well

If it is the same Tommorrow's World that is on TechTV, then we dont need to see TM hosted naked

one of the reactors @ TMI is offline as well, but because it almost melted down, and is still highly radioactive, not just closed
yes, you are right, my tour was before 9/11 and they probably dont do tours of the island anymore, and the security there is now really high
