Limits to Physics Insight
To turn it around, there may well be physics that we can only learn via records saved by ancient aliens - which gives us another good reason to seek such aliens. Krauss was at first scheduled to speak at that recent SETI workshop - it ...
Fermilab physicist wins congressional seat
Physics Today: Physicist Bill Foster may be the only democrat candidate running for Congressional office that has had an entire section of his campaign web site devoted to the particle accelerators and superconducting magnets. ...
Avoiding heat death at the end of the Universe
The second law of thermodynamics is a bummer. It says that the entropy of an isolated system will increase with time. It’s the reason why teacups break when they fall, why smashing eggs is easier than mending them and why teenagers’ ...
The Physics of space warfare: gravity in the ether streams
In the meantime, however, I shall be content to explain a little about the physics of space war-fare a thousand years ago. All the human ships–apart from a few crafty pirates–had to sail through space in the ether streams that connected ...
The physics of feet
How is it possible that shoes that seemed comfortable and awesome yesterday when I bought them were tight and weird and chaffing today? I hate that. And it’s not that bought-the-shoes-in-the-morning thing; I tried these bad boys on at ...
PISA and TIMMS
This keynote from the Mathematics Summer School looked at international assessment of students mathematical ability. Sue Thomson presentation. Workshop discussion points. The following are a collection ofpoints that were raised in the ...
In which Lindsay attempts to teach herself Physics…
Am I wrong, or do photons with wavelengths in the visible light spectrum interact with matter far more frequently than photons of different wavelengths? For example, visible light is reflected/absorbed by matter - thus allowing us to ...
Carbon Output Must Near Zero To Avert Danger, New Studies Say
Washington Post: The task of cutting greenhouse gas emissions enough to avert a dangerous rise in global temperatures may be far more difficult than previous research suggested, say scientists who have just published studies indicating ...
Westinghouse buys into South Africa's Pebble Bed Modular Reactor ...
Reuters: South Africa's advanced nuclear reactor technology programme will include US-based Westinghouse Electric as a partner and a new shareholders' contract is expected by the end of the month, an official said last week. ...
A More Accurate Clock, and Fine Structure Constant Isn't Changing
Talk about killing 2 birds with one stone. A new paper out of physicists from NIST has managed to accomplish to very important task. The first is the use of an optical clock that is way more sensitive and accurate than the atomic clock. ...
