Links to other web sites

Updated a little March 1, 2000.

Many more sites to be added, but so little time. Check in again, you cannot have tried them all!

The chaos on these pages may vary from time to time. A fact that in itself should merit another visit, soon, since things may have improved. In spite of increasing entropy, ds = (du + pdv)/T >= dq/T

Check when the page was last updated! Something interesting may have been added since your latest visit. Or, more likely, have been lost…

Do not take the headers too seriously. I do not! It is a massive job to try to sort out all these links. Some may fit in several categories. One day maybe I will try to sort them out. One day… Until then: enjoy them!

Do something Useful!

or at least: let your computer do it!

If you, like I, do not shut down your computer over night (I just shut down the monitor) you can help in the search for Extra Terrestial Intelligence! The Arecibo radio telescope listens for signals around the Hydrogen line near 1.42 GHz, the most likely spot someone would chose for radio contacts since this frequency is listened to with sensitive radio telescopes. Until one find signals there it is all noise, just like the noise on an empty TV channel. By sifting through the noise with powerful numerical analysis signals weaker then the noise can be detected, if they are there. The computer power needed for this is immense. SETI has not made it possible to download a little block of Arecibo recording and you can let your computer gnaw away on it when it is not doing anything else. The whole thing appears like a "screen saver" so when you need your computer it disappears into the background. At the most you get a 30 s wait while it finishes off some calculation. In my 66 MHz 486 it seems like it will take 540 hours to complete the calculations in my block. Then the program will call home, upload the result and download a new block. If your machine finds Extra Terrestial Life, you will get a bit of fame as well! So go to http://setiathome.ssi.berkeley.edu where you in one swoop can download the program and the data to be crunched!

SCIENCE

The SCIENCE magazine has recently begun to publish links to interesting sites. There seem to be such a treasure of sites that I decided to place some of them in a group of their own here:

(In the latest SCIENCE there was a funny coincidence! I suspect a Freudian slip. The excellent domain http://micro.magnet.fsu.edu/micro/gallery.html is introduced on their page "NetWatch" that I have most of the quotes below from. As a comment to the domain they write: "Magnified 2000 times Ben & Jerry's ice cream looks tie-dyed, champagne crystals bubble, and potassium nitrate from gunpowder bursts from the slide in Technicolor blazes.")

A daring move to mention Ben & Jerry on the same page as gun powder! B & J are mot only a couple of liberal, hypocrites. They are gun control freaks, buddies and supporters of Clinton and Sarah Brady, but it did not prevent them from hiring a CEO from Winchester! They do not talk so much about that.

Since they are gun control freaks I suggest that you avoid their products, unless you share their opinions. Anyhow, the micro.magnet domain is fantastic! Beautiful pictures through and of microscopes, a phenomenal collection of 'scopes in the microscope museum. Different illumination techniques and much, much, more!

How to view the 3D images:


By looking at something "behind" the screen the images above can be made to merge and appear as a 3D picture. This is the conventional way to view stereograms. Holding a vertical screen from between the images and your nose may also help to view them. Once the picture appears, remove the screen.

If you do not succeed with the "behind the screen" scheme, try this one! Hold a pencil in front of you, about halfway to the screen. Look at the pencil! In the background the images seem to merge. Focus on the images and slowly remove the pencil. This is the "cross eyed" way of viewing a stereogram, but the result is just as good as the regular way. Select the one that you find easiest. The knot site has both versions available. An intelligent move.

Weather and Web-Camera sites

Real Men seldom consult regular encyclopedias. This is mostly because Real Man already knows what he needs to know. Besides, encyclopedias are full of irrelevant stuff. Ethnology and Arts! They are edited by liberals who avoid subjects of interest to Real Men. Things that go whizz-bang.

Marc Sylwan was one of these remarkable men who has more brains than contained in an average city block. An accomplished writer and artist, he also designed this ingenious "Meccano" erection kit in the early 50s. I recall seeing it, through the store display window. The price was way out of reach for me, quite expensive for most I think, and it sort of faded away.

In the early 90s I contacted him for to see if we could not revive the system. On a visit to Stockholm in July 1992 I met Marc. By then FAC (derived from the Latin "facere", meaning "to do") had varnished. Some dude had somehow got the ownership of the tools and the rights. (Now some other 'dude' seems to have it!) Marc did not want to listen to any talk about reviving the old FAC anyway. He had a new design based on an extruded X-profile backbone. Of all this came nothing and a year later he was dead. I have a few catalogs with pieces and things built of FAC and I will soon scan them in here below. Beautiful illustrations, made by Marc himself!
