The Japanese have come up with a swimming snake robot:

Ronald Mallett is a university professor and a physicist. He believes time travel is possible, has a theory about how it can be done, and is working on a time machine:

The first dynamically-balanced robot, Dexter, learns to walk:

Here’s another robot, called Murata Boy, that can ride bicycles:

A home-made anti-gravity kit. Could be a hoax, but then again, I haven’t tried it out for myself, so I don’t know:

A demonstration of the principle of atomic halving through noodle-making. Awesome!

The FLIP is a research vessel that can literally flip to a vertical position while in water. It’s designed so its stern submerges deep underwater. It becomes incredibly stable that way, and this allows scientists to perform very precise measurements at sea.

I like to see scientific principles at work in everyday activities. Here are a few videos that illustrate this. Enjoy the weekend!

Galileo postulated that objects fall at the same speed in a vacuum, regardless of their weight. When we got to the moon, they did this experiment on live TV:

Here’s a bar trick that involves simple density physics:

Another bar trick involves simple dimension estimations:

Handling molten glass is an art and science onto itself. Molding it into shape, whether by blowing into it or by using tools, while it’s still white hot, takes knowledge about materials, temperatures, talent and a lot of hard work. It looks easy in this video, but it isn’t.

The Aardvark is designed to take out land mines. Its action is simple. It rotates chains with attached deadweights at high speed, combing through the ground. When it hits a landmine, they go off. The vehicle is heavily plated, and incurs no damage. It’s really cool to see physics and chemistry in action. Can you spot the different forces at work?

This next video shows what happens when water freezes: it expands. Because in this particular location the water is surrounded by rocks, the extra volume of ice has no place to go but up. It’s an unsettling sight, but it’s just a simple natural phenomenon.

The ferrofluid sculpture you’re about to see made the rounds a while ago. It’s a crowd pleaser, but it works based on magnetic forces. The fluid is filled with iron particles, which are magnetized. Electricity is likely used to create a magnetic field which varies in size and force, allowing the artist or a programmable chip to control the fluid’s movement.

How many of my photos were stolen?

For the moment, this is a rhetorical question. I’ve been re-thinking the way I publish my photos online in view of the recent and very prominent theft of Rebekka Guðleifsdóttir‘s photos from Flickr. Call me naive, but I really believed, and still would like to believe, that people will wish to stay legal and pay for the right to use my photos, especially for commercial purposes. That’s why I’ve been publishing my photos at full resolution. I wanted folks who weren’t able to pay (developing countries, for instance), or only wanted a nice desktop background, to be able to download a photo of mine and enjoy it without financial obstacles.

But I talked with my brother this morning, and he told me some things that made me think twice about my approach. He’s a professor at a university in Transylvania (Romania), and he does a lot of field research in ethnology and religion. He takes a lot of photos, and shoots a lot of video. When people ask him for copies of his work, he’s very nice about it and does so, hoping they’ll respect his academic work and cite him or ask for his permission when they use it. But he’s been finding out that they don’t. They’ll reuse his photos and his videos, and he won’t hear about it until he sees his work somewhere else. Just recently, someone entered one of his videos in a contest as their own creation, and he found out about it only after that person won. It was very disheartening. He’s now thinking of watermarking both his videos and photos, and of only publishing lower resolution copies on the Internet. He’s tired of constant theft and no attribution.

So I had to ask myself: how many of my photos have already been stolen? I haven’t yet heard of or seen a particular instance, but I also haven’t really looked around to see. It’s probably just a matter of time before I start finding my work in someone else’s portfolio, website or printed materials. When you combine high-resolution photos with people that have no respect whatsoever for someone else’s hard work, you’re asking for trouble. As much as I’d like to believe otherwise, good people, those that respect other people’s property, are few and far between, and it’s best not to tempt the thieves or uneducated ones by making good photos easily available.

I’ve taken some steps already. I used to upload to Flickr at full resolution. Not anymore. Since they offered Rebekkah no help whatsoever, and even deleted the photo where she complained of image theft, along with the thousands of comments that she received there, I’ve lost respect for them. If that’s how they’re going to treat one of their best users, then I sincerely hope they get what’s coming to them, and I hope it’s a wallop.

I may also start to watermark my images. As much as I hate this (it uglifies an image, imo), I’ll do it, just to make it harder to pass my photos around without crediting them properly. I may also start to copyright my photography with the Library of Congress, and pursue damages to the full letter of the law (up to $150,000 per incident).

Finally, I may also stop uploading at full res to Zooomr. I keep waiting for them to push out the Mark III upgrade, and it seems that every time Kris is ready to do it, something happens to stop it. This week was the third time the promised upgrade didn’t materialize, and I’m pretty disappointed. Mark III is supposed to have this really nice image theft prevention built in, so I could continue to upload a full res, but restrict the sizes available to casual visitors or even my contacts at certain resolutions, and only make the full res size available to buyers. But if Mark III doesn’t show up any time soon — and since Zooomr has no photo replace feature like Flickr — I may just delete all of my photos, or make them all private. I do not want to see my hard work go to waste.

It’s a real shame that we can’t function equitably as a society, at the local, state, national or global level. If only everyone would respect other people’s property (physical or intellectual), things would work a lot better. One would think the concept of property has been around long enough for most people and cultures to grasp it…

Michael J. Fox campaigns for stem cell research

Michael J. Fox appeared in some TV ads recently, to support stem cell research for Parkinson’s disease. The ads showed him moving uncontrollably, due to Parkinson’s. They were candid, and truthful. I’ve always liked Michael as an actor, and I thought he’s been a real gentleman throughout his ordeal with Parkinson’s. I agree with him, and with the ads. Stem cell research should be allowed, because it holds the potential for so many cures. So I was shocked to hear that Rush Limbaugh — although it shouldn’t be a surprise that he’s callous and inconsiderate — accused Michael of faking it in the ads. I love Michael’s response, which shows, again, how much of a gentleman he is:

“The notion that you could calculate for effect … People out there with Parkinson’s are going, would that we could.”

If I had been in his place, I wouldn’t have minced my words — and perhaps, that’s why I’m not in his place. Bravo to you, Michael! Keep up the fantastic work you’re doing, and I do hope they find a cure for Parkinson’s soon!
