Negative resistance

If 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… Continue reading Negative resistance

Do the math

There 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. TR says, So how are errors distributed among these programs? It would… Continue reading Do the math

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.. Then they ask the National Academy of Sciences’ Science and Entertainment Exchange to reccommend them experts to answer the questions. Their first question came to me, and it was about gray goo …… Continue reading Codex Futurius on Gray Goo

Solar progress

Two 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.… Continue reading Solar progress

Soft tough DNA material

From 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. At the same time, the material must be very… Continue reading Soft tough DNA material

Playing with Wolfram|Alpha

The highly anticipated Wolfram|Alpha site came online over the weekend, and here are some first impressions: They need a little work on the html — this was Firefox, but it looked the same on Konqueror.

Diamondoid nanotechnology

University of Ulster Scientists Make a Nanorod Breakthrough Engineers 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)… Continue reading Diamondoid nanotechnology

Science art

A nice display of serendipitous artistic images found while doing science, at Princeton: Hat-tip to Eurekalert.

Antimatter

From 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. Based on Dan Brown’s best-selling novel, this major motion picture, starring Tom Hanks and directed by Ron Howard, focuses… Continue reading Antimatter

Why we need Fab

I suspect many readers have seen Neil Gershenfeld’s TED talk on fab labs, or read his book. In particular, notice the part where he comments that fabs are following the track of computers, currently in the minicomputer stage. You can see the same progression in my keynote for a SME meeting a couple of years… Continue reading Why we need Fab
