Publicity Gimmick OR Malfunction?

waterless

One of these days I was driving behind this van.

In a sunny day, the windshield wiper was working. Usually a windshield wiper working without any rain (water) for any extended period damages the glass.

But paying attention to the van I could read “waterless”.

Prof. Bruce Bolt died

Prof. Bruce Bolt died.

I worked with him, in 1986, at Berkeley, and we were expected to have a get together in November this year.

Last December we had lunch in San Francisco. At that time he looked OK.

Geophysical Traditions

19th of July

Every year, in the 19th of July we have a tradition. We book a restaurant for the all evening and most of the people, in Portugal, with links to geophysics come to the gathering.

At least 90% of then have been one (or are) my profs, my collegs or my students. Some even fit in more of those groups.

We eat, we drink, we talk, we make speeches, etc., all evening.

19th of July is the birthday of the older living professor in geophysics, at the University of Lisbon.

The Trouble with Math

IMG_3301

I rarely see TV on real time. I rather record the programs I want to watch.

That fits well with my schedule that is sometime unusual and, this way, I can see most programs with double speed and no commercials, saving a lot of time.

“Showview” consoles (we can see my 3 sets in the pic) are very handy if you want to program all your recorders in the beginning of the month without much work. I had been using then for ages.

However they have become useless because Portuguese TV-guides stop printing the numerical codes for each program.

Things (my box camera)

Brownie D Box camere 3

Brownie D Box Camera 1

The beginning of the (last) century was the beginning of mass production.

The most known example is, of course, the "Ford T". But a very good example, also, is the "Kodak Brownie" the first "box camera" and the first camera build to be build for the masses. With minor improvements this camera has been produced until the '70s.

I cannot afford a "Ford T", but I have this nice "Brownie", shown in the pictures. I found this camera, in the attic, when I was perhaps 14 years old. At that time it worked faultless. Unfortunately it uses a kind of film that is not available anymore (some adaptation is possible to use other kind of film, though) so I cannot assess its present condition.

This particular camera build, perhaps, in the '40 or in the '50, has, as the most curious characteristic, the lateral blade we can pull out to insert an extra lens to decrease the focal distance. Working as a sort of macro lens it was build to be use in portrait photos (i.e. at medium-close range).

Note also the 2 identical "half a periscope" visors. Each one is linked to one of the two identical small lens in the from that give this camera an anthropomorphic aspect. The camera can be used in 2 positions and each visor has been build to use in each of the positions.

David and Goliath

david_and_golias

I like this picture a lot. As you all probably know I have been a supporter of the “no software patents” campaign.

The “pro software parents” movement, fulled by the resources of big companies and bureaucratic organizations, lobbied heavily.

Although the most known example was the “free ice cream”, they have, also, used a boat to ask for support of the “CII Directive”.

The “no software patents movement”, is mainly rooted in small size companies, almost all programmers and in academia.

Although the odds seem to favor the first, the “no software patents” has shown a lot of imagination. In the image, they got their own boat and allowed the photographer to capture the picture.

And the "CII Directive" was NOT approved.

Blowing up a comet for the 4th of July (III)

deep impact1

deep_impact3


myself_on_national_TV

The get-together to follow the comet impact went very well. We got a big screen where we project, at will, the NASA TV (relayed throw ESA TV) or the screen of a Internet connected PC.

Although very early in the morning (he session started at 06:30, with the climax about 07:00), we had a very friendly and enthusiastic audience, so most of the time the commentators where not on central stage, but mangling with the people ( sometimes forming small groups around one of the large number of portables computers in the room).

As far as I understand all national TV channels, except SIC (channel 3) where there and we had a direct at 07:00 on channel 1 news service (I have been told). Several newspapers were also present.

A friend of mine has digitally recorded – and sent to me - a TVI news flash, broadcasted at lunchtime and I captured a frame seen above.

Blowing up a comet for the 4th of July


At around 06:52 – Lisbon Time - (or 05:52 UTC/GMT) the 4th of July, NASA's Deep Impact Mission is going to send an impactor to blow a hole in the "Tempel 1" comet.

The impactor is just a piece of metal with, more or less, the same size and shape of a small table.

Perhaps, in the future, people will look at this mission as the first trying to "explode" a comet, routine procedure to save the earth from catastrophic encounters (a subject science-fiction as visited several times, just remember the movie pictures: "Deep Impact" and "Armageddon”).

Since the internal structure of the comets is not know, there is no clear idea about what is going to happen and if the event would be seen from Earth (with a telescope).

Several other probes, beside “Deep Impact”, will try to collect info during the collision. The Hubble Space Telescope will take a snapshot.

There are not going to use explosives, but do not be fooled by that; with the velocity involved, and since the kinetic energy is proportional to de SQUARE of the velocity (i.e. each time you double the velocity, you multiply the energy by 4) the shock is going to be quite "explosive" (as everybody who as read "The Moon is an Harsh Mistress", my Robert A. Heinlein favorite book, know).

The velocity of impact is about 37 100 Km/h (30 times the speed of sound in the Earth surface). With 364 kg the impactor will reach to comet with almost 2E10 Joules of energy, the equivalent of around 5 tons of TNT.

Probably I will joint nuclio [ link: http://www.nuclio.pt ] to follow the event using a ESA satellite link (C-band?) . (Programs also available ay the internet)

Things (my slide rule)

slide rule (tri-log)

This is a picture of my slide rule. It is a "Aristo trig-log", because it has 3 logarithm scales (plus 3 INVERSE logarithms scales). In my last year at high scool and in my first two years at the University I became very proficient in using slide rules for all sort of computations and the slide rule shown was quite precise.

My favorite slide rule, however, was a "multi-log" (5+5 log scales). With half the size of this tri-log it was not so precise, but it was more powerful and, besides, it fitted well in my coat pocket.

Around 1975 electronic calculators became very cheap and, around 1977, I made some money tutoring high school students and I bought a programmable Texas Calculator. I never used any of my slide rules again.

I lost some familiarity with numbers, and some inside, but I gain a lot of significant figures.

A Cool Picture

Hokkaido University  (Hokkaido Island / Sapporo City / Japan)



Now that the weather is becoming hotter by the day (at least in the Northern Hemisphere...) I am showing a cool picture. It was taken by Professor Hideki Shimamura in the campus of the Hokkaido University, in Sapporo, Japan.

To have an idea of the place where the picture was taken, click in the following link:

http://www.mapquest.com/maps/map.adp?latlongtype=decimal&latitude=43.08222&longitude=141.33917

(zoom in and out as you like)

The last time I have been to Hokkaido I didn't have a GPS yet. Because of that I have use maps to find the location, so this is just a rough approximation, perhaps with 1 Km of error.

Things (my rolleiflex)

rolleiflex



This use to be my father favorite camera. I try to keep it functional, but I do not use it often, because is clumsy and because I have to go special stores to buy the film and, latter, to process it (the film is not cheap, 5 times more expensive that the usual film for cameras).

It's a Twin Lens Reflex (TLR) Rolleiflex, probably the most famous camera - ever.

Twins means that we have a set of lens to record the image in the film, and a duplicate set of lens to produce the same image in the "visor" - OK parallax is a (solvable) problem.

That’s why we see the “8 shaped” objective in the front. In reality it’s the 2 twin objectives side by side.

This machine uses 6cm x 6 cm film, with 56mm X 56 mm negatives, witch compares to the 35 mm film, widely used today, with a 36mm x 24mm negative. The increased area of the negative allows a better quality of the photo (if all other parameters are equal). This makes the difference, for example, if you enlarge the picture in order to frame and hang it on the wall. It also compensates, somehow, the lack of zoom lens.
