Surprises in steel: The mystery behind Detroit entrepreneur's revolutionary Flash Bainite
A Detroit entrepreneur surprised academics when he invented a heat-treatment that makes steel 7 percent stronger than any steel on record – in less than 10 seconds. That steel, now trademarked as Flash Bainite, has tested stronger and more shock-absorbing than the most common titanium alloys used by industry. Now Gary Cola is helping researchers at Ohio State University to better understand the science behind the new treatment, called flash processing. What they've discovered may hold the key to making cars and military vehicles lighter, stronger, and more fuel-efficient. In the current issue of Materials Science and Technology, the inventor and his Ohio State partners describe how rapidly heating and cooling steel sheets changes the microstructure inside the alloy to make it stronger and less brittle. "Steel is what we would call a 'mature technology.' Yet, when inventor Gary Cola initially approached him, Babu didn't know what to think. Cola's entire process took less than 10 seconds.

An Essay by Einstein -- The World As I See It
"How strange is the lot of us mortals! Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people -- first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving... "I have never looked upon ease and happiness as ends in themselves -- this critical basis I call the ideal of a pigsty. "My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities.

5 Statistics Problems That Will Change The Way You See The World
Once the population of an office hits 366 people, it's a certainty that two people in your office have the same birthday, since there are only 365 possible days of birth. Still, assuming that each birth date (except February 29) is equally likely, it turns out that once your office has 57 people in it there is a 99% chance that two of them share a birthday. When there is 23 people, that probability is 50%. Here's why. Instead of calculating the probability that two people share a birthday, instead calculate the converse, probability that two people don't share a birthday. Since these are mutually exclusive scenarios, first probability plus the second probability has to equal 1. Here's how we figure this out, then. Select two people in the office. 365/365 x 364/365 x 363/365 x 362/365 x ... x 343/365 = 0.4927. So, the probability that nobody in an office of 23 people share a birthday is 0.4927, or 49.3%.

Zombie ants have fungus on the brain, new research reveals
New research has revealed how infection by a parasitic fungus dramatically changes the behavior of tropical carpenter ants (species Camponotus leonardi), causing them to become zombie-like and to die at a spot that has optimal reproduction conditions for the fungus. The multinational research team studied ants living high up in the rainforest canopy in Thailand. A paper describing the research was published in the BioMed Central open-access journal BMC Ecology on May 9. To see photos related to this research, visit online. "The behavior of these infected zombie ants essentially causes their bodies to become an extension of the fungus's own phenotype, as non-infected ants never behave in this way," said David P. Using transmission-electron and light microscopes, the researchers were able to look inside the ant in order to determine the effect of the fungus on the ant.

Demystifying the Natural Logarithm (ln)
After understanding the exponential function, our next target is the natural logarithm. Given how the natural log is described in math books, there’s little “natural” about it: it’s defined as the inverse of e^x, a strange enough exponent already. But there’s a fresh, intuitive explanation: The natural log gives you the time needed to reach a certain level of growth. Suppose you have an investment in gummy bears (who doesn’t?) e and the Natural Log are twins: e^x is the amount of continuous growth after a certain amount of time.Natural Log (ln) is the amount of time needed to reach a certain level of continuous growth Not too bad, right? E is About Growth The number e is about continuous growth. We can take any combination of rate and time (50% for 4 years) and convert the rate to 100% for convenience (giving us 100% for 2 years). Intuitively, e^x means: e^x is a scaling factor, showing us how much growth we’d get after x units of time. Natural Log is About Time For example: e^3 is 20.08. Zero.

Most unusally, our sophomore-level labs cover much of the material usually taught in Jr. lab. Suzannne Amador Kane I also maintain a website with more information about medical physics-related labs. Sound Lab (intro level) We also have a related curriculum on science ethics that I will be posting shortly. AAPT listserv on advanced lab materials Lab Manual for Nanoscale Science and Technology (University of Wisconsin's MRSEC)--has excellent online materials with many good ideas.

Lightning Can Open Doors to Parallel Worlds -- Paranormal News -- Your Source for UFO and Paranormal Related Information
Approximately 10 years ago, children began to disappear from an amusement park of the British town of Kent. The kids would enter the hall of mirrors and never came out. The local police ran off their legs. Recently, a psychic lady announced that she knew where the kids were. According to her, there was a door to the other world behind one of the mirrors in the amusement park. We live in a 3-D space where everything is measured by height, width and length, and we are only capable of thinking within these limits. There is the so-called "string theory" popular in contemporary physics. "There can be up to 26 dimensions, but they are sort of folded, so we cannot see them. If the fourth and other dimensions exist, where do they lead? In 1931, Charles Fort, American researcher, introduced the term "teleportation spaces." These were areas where sudden teleportation was possible and where the "doors" to parallel worlds open. There are plenty of witnesses who allegedly traveled to other worlds.
