The delight of postage stamps

Just got a letter from the UK, and it had this colorful stamp on it.

Postage Stamp

For an instant, I felt that special twinge of joy that an interesting stamp elicits; only after a moment did I remember that (a) I no longer collect stamps, not since I was a kid I don’t, and (b) none of my friends does, nor do they have kids that do that I might give the stamp to.

This is a shame, really, because postage stamps have a built-in ability to delight. They are often beautiful, they come from wondrous distant lands, they have a story to tell in their miniature image, and they are eminently collectible. In this way, every letter that you or your circle of friends and relatives received had the potential to surprise you with a “bonus”, a tiny capsule of serendipity where the stamps it bore could be boring or fascinating, depending on the luck of the draw.

All this may soon be over. I don’t know whether stamp collecting is on the decline (I suspect serious adult collectors do exist, but children may be more into video games these days). But the stamps themselves may soon be obsolete. People send less personal letters since the advent of email, and I’ve just read that the UK is planning postage stickers you can buy online and print out, and these have a bar code, not a picture (they also took out the queen’s ever-youthful profile we see in the stamp above, causing much consternation).

But meanwhile stamps still exist, and I know of one guy who makes full use of their joy-creating potential. He is a fellow History-of-Computing collector, and an eBay seller of slide rules; when I buy one from him it invariably arrives in an envelope covered with a mosaic of small-denomination stamps, each one different, all beautiful.

The riot of color is so cheerful that I collect these envelopes. What a nice way to delight one’s customers!

Couch potatoes vs. Movie theaters

One sign of the times is that movie halls are closing one by one around us, victims to the surge in electronic alternatives. We know this from direct observation – they really are closing – but I had an unexpected demonstration of this fact in a TV ad.

The ad was by the Hot cable company we subscribe to, and was aimed to convince us to use their Video on Demand service. It showed how difficult it supposedly is to get a movie without their VOD: it graphically showed how you need to go down 20 stairs to the street, walk a mile to the Videomat, check if it has a movie you want. No? Walk another mile to the video store, get the movie, walk back… you get the idea.

Nice ad, but what amused me is that 20 years ago they would’ve said “Go down 20 stairs, get in the car, ride downtown, and enter the movie theater”. These days, that just isn’t seen as a viable alternative! You’re expected to either slump on the couch in front of a cable movie, or rent a video and slump in front of that… and these guys want to deprive you of even the little exercise you’d get walking to the video store  :-(

Where Computing meets Pseudoscience

biorhythmcalculator.jpgJust posted a new article on my History of Computing site: Biorhythmic calculators.

I have three of these wondrous devices, mechanical servants to a debunked theory. They use three different design approaches to achieve the same goal, and their mechanisms are therefore composed of the same functional components implemented in completely different ways.

Go take a look!

FameLab again!

Last year I posted about FameLab, the science communication competition organized by the British Council in the Jerusalem Science Museum. Well, here it comes again, and today I’m a judge again. Like before, we get treated to a group of fine young students presenting diverse scientific subjects in only 3 (yes, three!) minutes each. Fascinating!

I also learned an interesting thing: the British Council is working hard to empower the winners to propagate science knowledge. Not only do they receive presentation skills training, they also get to attend international get together where winners from diverse countries meet face to face to exchange views, learn from each other, and figure ways to promote Science education. This is really a wonderful program!

Those conservative business cards…

Business cards have been around for a long time – very long, if you count visiting cards – so we should not be surprised if they tend to have an innate inertia to them. Still, business has changed so much in recent years – isn’t it time that the cards paid attention?

I was scanning a batch of business cards I got in a conference recently when I noticed an interesting fact: they may come in many designs and colors, but 90% of cards will have the contact information in the following order:

Physical address
Phone number
Fax number
Mobile number
Email address
Web site URL (if any)

Now this is interesting, because it has two attributes:

  1. It follows the approximate historical order the various technologies appeared in (first we had office buildings, then telephones, then faxes, etc.)
  2. It gives the items in reverse order in terms of usefulness, the least useful at the top: in today’s virtual, mobile, global world, we would most often use email to reach people, or a cellphone if they have one; faxes are not yet gone but may soon be, and physical addresses are only of marginal use in a “work anywhere” culture.

I had a friend, a master blogger and geek, who once said if he had his way he’d simply put on his card his name and “Google me!” – now that’s modern thinking for you! The closest you get to this are Moo minicards, those miniature cards that barely have room for a name, job role and email address.

Now that I noticed this I checked my own new card that I made after leaving Intel – and guess what, I had it almost right in terms of descending importance:

Name
Web site URL
Email address
Physical address
Mobile number (the only phone I use)
Fax number

Only the physical address stayed higher than it should be…

Holes, Honesty and Hand cream

Neutrogena Norwegian Formula hand cream“Truth in advertising” sometimes seems an oxymoron, and the cosmetics industry is hardly where you’d expect to find much of it. So hats off to Neutrogena’s Norwegian Formula hand cream, whose statement on the tube that it “instantly relieves dry or chapped hands – just a dab needed” is absolutely correct. They claim it was devised from the experience of Nordic fishermen with the effect of fish oils; be that as it may, I can attest that this formula really can handle chapped skin that would laugh at your usual hand lotion.

But more to the point, just a dab is really all it takes, and here the manufacturer did something really amazing: it designed the tube to ensure you don’t use more than that dab. Look at the photo below, which compares the tube of this fishy formula with another cream. The hole the cream comes through is barely a pinprick. Obviously, this spares the consumer’s money – at the expense of the vendor’s profit. Wow!

Neutrogena Norwegian Formula and another brand

Which reminds me of the story of the guy who came to a toothpaste company and proposed they give him a megabuck if they like his idea for increasing profits: he then told them to enlarge the hole at the end of the tube, since consumers measure out paste by length, not volume. The guy got his money (though I can find no confirmation that this ever happened – can you?) because the toothpaste manufacturer was not as honest as the makers of the Norwegian hand cream discussed here…

What’s in the box?

Care to guess what delightfully well-designed product is hidden inside this elegant 5 inch long metal case?

Mystery Case

Check it out in the latest article on the Possibly Interesting web site!

Can you guess what this device does?

They say that form follows function. So – take a look at the form of this strange device, which stands about a meter tall. Can you guess its function?

Smell Display Device at teh Potsdam Biosphere

No, it isn’t a trashcan with dreadlocks.

I saw this thing in the Biosphere at Potsdam. This pleasant museum is smaller and less ambitious (should I say, less pretentious?) than the one in Arizona, and serves very well to exhibit different ecosystems to the visiting public.

The item you see here is a display device for displaying smells. You sniff the end of a tube to get a whiff of the plant shown on the round image below it.

Did you guess?…

Watch the beauty!

These days, every product and service come with scary warnings intended to cover the maker’s back side in case you harm yourself. Electrical appliances warn you not to drop them in water (Duh!), restaurant menus tell you you can die by eating their food (not here, thank God, but in the US they do), coffee cups tell you their content is hot, an so on ad nauseam.

But the strangest, and strangely endearing, manifestation of this must be the sign we saw at the entrance to the Baha’i gardens on the slopes of Mt. Carmel in Haifa. Here is the sign:

Bahai Gardens sign

What they tells us is that the beauty of the gardens is such that we might be distracted into not watching our step and falling down one of the hundreds of steps that take you downhill!

And I must hand it to them… they aren’t exaggerating. These gardens are mind bogglingly serene and beautiful, though the risk is probably from trying to snap photos instead of looking where one is walking. The photo below shows only a small portion of the gardens, with the shrine of the Bab, a prophet of the Baha’i religion, in the background, and the port of Haifa even farther out.

The Bahai Gardens in Haifa

This small photo can hardly do justice to what we saw there, but may give you a hint. The real thing is simply breathtaking!

Babylonian memory technology

A gem I saw in a museum recently: this is a large cuneiform-inscribed cylinder, maybe 3-4 inches thick, which describes the building activities of king Nebuchadnezzar (better known in the bible for his opposite exploit when he destroyed Jerusalem in 587 BC).

Babylonian Cuneiform Cylinder

Anyway, in one of those moments of associative memory, it struck me how similar this looked to the contact-studded drum memory devices of the ABC, or Atanasoff-Berry Computer, one of the earliest electronic computers (1941), pictured below at the left. One is also reminded of the magnetic drums that served computers for memory in the 1950s, like the one to its right.

Computer Memory Drums

The idea of using a drum for computer storage makes good sense in terms of allowing it to be scanned easily by rotating it; but the Babylonians probably used this form because it allows you to cram much text (and many construction exploits, if you’re a busy king like Nebuchadnezzar, he of the hanging gardens of Babylon) into a relatively compact object.

Also worth noting: The king’s memory cylinder is still readable after more than 26 centuries; so, can you read your 5-1/4 inch floppies any longer?
