Foresight Update 23.21: Solar progress- May 21, 2009Discuss these news stories at http://foresight.org/nanodot. Top News of the WeekSolar progressTwo new items that are follow-ons to the Moore's Law for Energy thread. A story at Technology Review about new electronics that improve the usable power from existing solar panels by 5-25%. The advance is new smarter electronics that allows for an inverter for each panel instead of one big one for the whole system… In this issue:
Foresight Events – Lectures Negative resistanceIf you connect a 12-volt battery to a 4-ohm lamp, 3 amps of current will flow through the circuit by Ohm's Law, V=IR. Power = VI = 36 watts will be dissipated by the lamp. If you add a 2-ohm resistor in series with the lamp, the resistances add to 6 ohms, the current is 2 amps and the circuit thus dissipates 24 watts. The voltage across the resistor is 4 volts so it dissipates 8 watts and the lamp gets 8 volts and dissipates 16… Do the mathThere is at Technology Review's arXiv blog an article "How to find bugs in giant software programs." It's an overview of a paper on arXiv which is a statistical study of program sizes and bug distributions in the Eclipse dataset of Java programs… Codex Futurius on Gray Goo"Codex Futurius" is a project of Discover Magazine's Science Not Fiction blog in which they ask science questions raised by science fiction… Soft tough DNA materialFrom PhysOrg: Implants and scaffolding for tissue growth require porous, soft materials — which are usually very fragile. Because many biological tissues are regularly subjected to intense mechanical loads, it is also important that the implant material have comparable elasticity in order to avoid inflammation… Playing with Wolfram|AlphaThe highly anticipated Wolfram|Alpha site came online over the weekend, and here are some first impressions: alpha on firefox. They need a little work on the html — this was Firefox, but it looked the same on Konqueror… Diamondoid nanotechnologyEngineers at the University of Ulster are the first researchers to create diamond nanorods with a diameter as thin as 2.1 nm, which is not only smaller than all the currently reported diamond 1D nanostructures (4-300 nm) but also smaller than the theoretical calculated value (2.7-9 nm) for energetically stable diamond nanorods… Science artA nice display of serendipitous artistic images found while doing science, at Princeton… AntimatterFrom Azonano: Physicists to Brief Media and Public on Real Science of Antimatter On May 15, 2009, Sony Pictures will release "Angels and Demons," and bring the world's largest particle physics laboratory to the silver screen… —Nanodot posts by J. Storrs Hall Foresight Events – LecturesForesight LecturesMay 28-29, 2009 June 17-18, 2009 August 20-22, 2009 Foreseeing Future TechnologiesAdvancements in technologies such as nanotech, robotics, and biotech are promising to make major differences in our lives in the not-too-distant future, as the Industrial Revolution did to the agrarian world — to do for the physical world what the computer and Internet have done to the world of information. Since 1986, the Foresight Institute has been in the forefront of a worldwide community of visionaries who work to help shape these possibilities into a positive, beneficial reality. If you would like to help us understand the potential of these technologies, and influence their direction, please consider becoming a member of the Foresight community. With your support, Foresight will continue to educate the general public on these technologies and what they will mean to our society. To join: Contact ForesightThe Foresight Institute Weekly News Digest has merged with Foresight Update and is emailed every week to 15,000 individuals in more than 125 countries. Foresight Institute is a member-supported organization. We offer membership levels appropriate to meet the needs and interests of individuals and companies.
