Many college entrance exams in the early s were specific to each school and required candidates to travel to the school to take the tests. The College Boarda consortium of colleges in the northeastern United States, was formed in to establish a nationally administered, uniform set of essay tests based on the curricula of the boarding schools that typically provided graduates to the colleges of the Ivy League and Seven Sistersamong others. Terman in particular thought that such tests could identify an innate " intelligence quotient " IQ in a person.
Log in to post comments By Hank Roberts not verified on 18 Sep permalink Did somebody tell said yahoo that his body temp is radiating blackbody microwave radiation? Think of the racial implications. Think of the noisy WiFi connections.
When the Devil strode the Earth onions appeared under his right foot and garlic under his left. Complainant is obviously a Luddite commie satanist. You can't take those people seriously - that is why we elect them to Congress, where they won't bother us.
If garlic wants to surf the Web, Rural Electrification will do stdies about supplying subsidized Cable access. Microwaves have lower frequencies than visible light. Lower even than infrared, which is emitted by everything around you.
Almost as low as radio waves. A cell is mostly water, and by volume DNA is quite a tiny target. So, the biggest threat to DNA is indirect: Of course there is still some direct UV damage to DNA, but the mechanism is lot more interesting than the simple blast-damage picture most people have.
To properly complete the analysis, you need to first sum up the total lifetime exposure to Wi-Fi radiation, and then compare that total energy against the energy delivered to the back of a crackpot's head by just a single dope-slap.
I suspect most people think they are being "beamed" directly into their antenna, not bathing their entire house and yours in electromagnetic radiation.
It is a question of intensity and modulation. Along a similar line, our brains operate with electromagnetic signals in the ELF range, so it must be a matter of epidemiology and experiment to discover if external fields in that range might pose a problem.
The one thing we know with confidence is that they will not produce cancer via the same mechanism that people associate with "radiation" such as x-rays or UV. As noted 14, in this respect microwaves are safer than the IR that provides heating from the wires in a toaster.

For one, the authority figures in question were not merely authority figures, but were so because they were experts in their field. You may not have meant it as such, but failing to distinguish lumps in experts with elected offices and political appointments.
For two, there were plenty of studies on which they based the claim. Every vaccine we use had to go through a screening process for effectiveness and safety. Just because they didn't do a study that singled out that one item until after the manufactrovercy, doesn't mean that there was an "entire lack of evidence of any kind.
For three, the ecperts by-and-large pointed out not that it was "perfectly safe," but that it was safe in the sense that the benefits far, far outweighed the potential, as they were unproven risks.
Log in to post comments By Mystyk not verified on 18 Sep permalink One thing that seems to be implied by the above discussion including comments is that, the higher you go in frequency, the worse the EM radiation will be on our bodies because the photons will have higher energy.
Electromagnetism and our biology aren't so simple. When you get up to 60 GHz, you get a different effect. EM radiation at that frequency is absorbed by moisture in the air, more than any other RF frequency, but can't even penetrate your skin.Mission-driven organization representing over 6, of the world’s leading colleges, schools, and other educational organizations.
