A phosphene is a phenomenon characterized by the experience of seeing light without light actually entering the eye.

putting the storage provider in a very awkward position as megaupload’s service contract has been cancelled but the data can’t be deleted as it might interfere with the court case.

Highly-enriched uranium from weapons stockpiles is displacing some 10,600 tonnes of U3O8 production from mines each year, and meets about 13% of world reactor requirements.

Henry Gustav Molaison (February 26, 1926 - December 2, 2008), famously known as HM or H.M., was an American memory disorder patient whose hippocampus, parahippocampal gyrus, and amygdala were surgically removed in an attempt to cure his epilepsy.

Reviews of material separated by a long period of time (“spaced”) yield more learning than reviews separated by a shorter period of time (“massed”);

Memory consolidation is a category of processes that stabilize a memory trace after the initial acquisition

Two-way communications handled 65 exabytes in 2007, dwarfed by broadcasting, which sent a whopping 2 zetabytes of data. But, while broadcasting is increasing at a linear rate, the advent of the Internet has given two-way transmissions a big boost, increasing the bytes transmitted by a factor of 29 in just 7 years.

“To put our findings in perspective, the 6.4*10^18 instructions per second that human kind can carry out on its general-purpose computers in 2007 are in the same ballpark area as the maximum number of nerve impulses executed by one human brain per second,”

Currently, almost every cable that lands in Asia goes through a choke point in the Middle East or the Luzon Strait between the Philippine and South China seas.

Cautery pen filaments get so hot that they can cut through flesh effortlessly. Physicians routinely use them for small surgical procedures.

One of [them] obviously, of course, involved with epilepsy. It turns out that stimulation of this nerve can actually desynchronize the EEG, where synchrony in the EEG is the sign of epilepsy, or of active seizure.

The endorsements decrease aggregate adult fiction sales; likely as a result of the endorsed books being more difficult than those that otherwise would have been purchased.

Sergeyev begins by adding a new axiom to the axiom of real numbers, which he calls the infinite unit axiom. This introduces grossone–the infinite unit.

Because it is governed by the other axioms of real numbers, grossone behaves much like one too. So it’s possible to multiply grossone, divide it, add to it and subtract from it, just as is possible with other real numbers.

Professor Robert Richardson, of Cornell University, New York, who won the Nobel physics prize in 1996 for his research on helium, argues that a helium party balloon should cost £75, to reflect the true value of the gas used. Yet you can buy enough helium to float 200 balloons for that price. “We are squandering an irreplaceable resource,” he says.

The developers used ‘/’ for flags. Then, when DOS 2.0 added directories, ‘/’ was already taken, so they used backslash for the directory separator.

After a median follow-up of 11 years in the core age group, the relative reduction in the risk of death from prostate cancer in the screening group was 21% (rate ratio, 0.79; 95% confidence interval [CI], 0.68 to 0.91; P=0.001), and 29% after adjustment for noncompliance. The absolute reduction in mortality in the screening group was 0.10 deaths per 1000 person-years or 1.07 deaths per 1000 men who underwent randomization. The rate ratio for death from prostate cancer during follow-up years 10 and 11 was 0.62 (95% CI, 0.45 to 0.85; P=0.003). To prevent one death from prostate cancer at 11 years of follow-up, 1055 men would need to be invited for screening and 37 cancers would need to be detected. There was no significant between-group difference in all-cause mortality.

As a world average, the per-person food availability for direct human consumption grew 19 percent to 2720 kilocalories per day in the three and a half decades to the mid-nineties

Bills and coins represent only 3 percent of Sweden’s economy, compared to an average of 9 percent in the eurozone and 7 percent in the U.S.

For Kierkegaard […], anxiety/dread/angst is unfocused fear. Kierkegaard uses the example of a man standing on the edge of a tall building or cliff. When the man looks over the edge, he experiences a focused fear of falling, but at the same time, the man feels a terrifying impulse to throw himself intentionally off the edge. That experience is anxiety or dread because of our complete freedom to choose to either throw oneself off or to stay put. The mere fact that one has the possibility and freedom to do something, even the most terrifying of possibilities, triggers immense feelings of dread.
