Gerard ’t Hooft, Theoretical Physics as a Challenge by Gerard 't Hooft Note: This web site will soon be removed from its present address. An updated and renewed version is available at: This is a web site for young students - and anyone else - who are (like me) thrilled by the challenges posed by real science, and who are - like me - determined to use their brains to discover new things about the physical world that we are living in. It so often happens that I receive mail - well-intended but totally useless - by amateur physicists who believe to have solved the world. It should be possible, these days, to collect all knowledge you need from the internet. I can tell you of my own experiences. Theoretical Physics is like a sky scraper. Note that this site NOT meant to be very pedagogical. Languages:English is a prerequisite. French, German, Spanish and Italian may be useful too, but they are not at all necessary.

The dos and don'ts of 99-cent stores Ah, dollar stores. We confess to dropping in occasionally for toilet paper and shower-curtain liners, but tend to view other items warily. Will cut-rate toothpaste lead to a root canal? First off, a little 99-cent store 101: Name brands show up in myriad ways: manufacturer surplus, company overstock, new packaging, product-renaming, misprinted labels and much more. Spices and herbs: These can cost upwards of $3 at regular grocery stores while Canadian-based Encore makes FDA-approved seasonings, spices and herbs that you can find at many Brooklyn dollar stores. Gift wrap: This is a brilliant item to start buying at a dollar store, because the person opening the gift probably isn’t going to notice if you spent $8.99 on the “good” paper from Target or not. Pregnancy tests: It can’t be, but it is. Shampoo: Often, dollar stores have name-brands like V05 and Suave for under $1.50, but don’t forget to try out Hairvitalize, Fruitamin and Johnson Parker’s line.
Physics of Collective Consciousness by Attila Grandpierre Attila Grandpierre, Ph.D. Konkoly Observatory of the Hungarian Academy of Sciences H-1525 Budapest P. O. Box 67., Hungary February 6, 1996 From: ABSTRACT: It is pointed out that the organisation of an organism necessarily involves fields which are the only means to make an approximately simultaneous tuning of the different subsystems of the organism-as-a-whole. 1. It is generally accepted that consciousness evolved parallel to the biological and social complexity of the living systems. 2. It is widely believed, that the way evolution manifest is from parts to the whole, from the inorganic matter through the unicellular organism towards the multicellular ones until the appearance of consciousness. This chain of thought places collective phenomena into the centre of evolution and the generation of consciousness. 3. Experiments show that collective biological fields may dominate the individual field (Popp, 1994). 4.

THE IRANIAN: Persian or Iranian? Behrouz Bahmani May 7, 2004 iranian.com After my recent piece on an imaginary coffee with Farah Pahlavi, and the expected 2 sides of the issue comments I received, being inherently sheytoon, I began thinking about what other hot topic I could exploit, I mean, explore. Sex? Too intimidating. Religion? Then out of the blue, an email buddy raised the debate of Persian vs Iranian again, and I knew I had my hot button topic! Nothing seems to get our blood boiling more than this issue. So what angle could I offer to stir up the controversy once more? As we all know (or do we?) The good professor further explains that the suggestion for this name change was first proposed by a (curiously but wisely nameless) Persian ambassador to Germany who at the time was being wooed by members of the growing Nazi movement, eager to build relations with other nations of Aryan ancestry. A PR makeover, if you will. By the end of WWII, all remnants of the word Persia and Persian had been wiped away. ) or "Iran".
8 shocking things we learned from Stephen Hawking's book From the idea that our universe is one among many, to the revelation that mathematician Pythagoras didn't actually invent the Pythagorean theorem, here are eight shocking things we learned from reading physicist Stephen Hawking's new book, "The Grand Design," written with fellow physicist Leonard Mlodinow of Caltech. The book, covering major questions about the nature and origin of the universe, was released Sept. 7 by its publisher, Bantam. 1. The past is possibility According to Hawking and Mlodinow, one consequence of the theory of quantum mechanics is that events in the past that were not directly observed did not happen in a definite way. Instead they happened in all possible ways. This is related to the probabilistic nature of matter and energy revealed by quantum mechanics: Unless forced to choose a particular state by direct interference from an outside observation, things will hover in a state of uncertainty. Yeah, we're still trying to wrap our brains around this. 2. 3. 4. 5. 6.
Mary Todd Lincoln Mary Ann Todd Lincoln (née Todd; December 13, 1818 – July 16, 1882) was the wife of the sixteenth President of the United States, Abraham Lincoln, and was First Lady of the United States from 1861 to 1865. A member of a large, wealthy Kentucky family, Mary was well educated. After living in the Todd House and a finishing school during her teens, she moved to Springfield, in Illinois where she lived for a time with her married sister Elizabeth Edwards. Before she married Abraham Lincoln, Mary was courted by his long-time political opponent Stephen A. Douglas. Mary Lincoln suffered from migraine headaches and other severe illnesses through much of her adult life. Early life and education[edit] Mary was born in Lexington, in Kentucky as the fourth of seven children of Robert Smith Todd, a banker, and Elizabeth (Parker) Todd.[1] Her family were slaveholders, and Mary was raised in comfort and refinement.[2] When Mary was six, her mother died.
