Genetics 101

If you were not sure that genetics was a science, you needed a controlled experiment. Here is the result of such an experiment:

Wonderbra ad based on pure illusion

Yves Roumazeilles — Wed, 07 Apr 2010 13:17:50 +0000

This ad for the generosity of a woman bra brand (try repeating this quickly!) is based upon a well-known optical illusion. Will men fall for this one?

Zoom into the Mandelbrot set

Yves Roumazeilles — Sun, 14 Mar 2010 13:04:28 +0000

The fashion of drawing fractals is a memory of the past (it was probably linked to the first appearance of computers able to collate the computing power for the needed calculations and the display capacity for complex images). But the pleasure is all mine to find this HD video which sends us into a Mandelbrot set, this fractal structure (which seems to never change whatever the observation scale – a little like the ever finely cut coast of Brittany).

So, here are 10 minutes of total fractal travel:

The zoom is so intense that the original fractal is larger than the known universe, but the last image gives details smaller than the smaller of nuclear physics particle.

9 love messages from Planet Earth

Yves Roumazeilles — Sat, 07 Feb 2009 13:22:31 +0000

You’d believe that our planet is in love. It can be read on its face (on its surface) merely under the form of pretty hearts nicely drawn.

9 other cases. Superb!

Stacey Whaley, fractals

Yves Roumazeilles — Sun, 07 Dec 2008 16:26:57 +0000

Stacey Whaley is a painter using the most modern tools available and depending heavily on the mathematical principles of fractals (those graphical figures that tend to repeat themselves at different scales when you zoom in or zoom out).

In most cases, when people follow this path, the result is quite predictable and there are a few compulsory forms (like the Mandelbrot set) that pop in the pictures. Please, check the admirable result of the example above. Stacey is able to create something that is clearly fractal and simultaneously bringing all the personal content that is the mark of the true artist.

Check all her work in http://intergalacticart.blogspot.com/, even if the updates are too few for our pleasure.

Test your color vision

Yves Roumazeilles — Sun, 23 Nov 2008 12:26:20 +0000

Are you colour-blind like 5% of European male population? This is the question that will receive an answer here. You will even know the exact form of colour-blindness is yours when browsing to test your colour vision.

You will have to check little images like the one here and indicate what you see (not everybody sees the same thing, it’s not as simple as you’d think first).

Then, the test will speak and you’ll know. It’s barely less precise that a pro optician or a physician eye/vision test. It’s based on exactly the same elements.

Camouflage in nature

Be a beta-tester

Yves Roumazeilles — Sun, 12 Oct 2008 10:15:48 +0000

If you have the heart of an adventurer, you may be interested to know that Ijust put in beta-test some new websites that I am working on.

YLovePhoto.com (site specializing in digital photography)
YLoveBigCats.com (about felines and other big cats)
YLoveIllusions.com (optical illusions)
YWantVisits.com (SEO, traffic optimisation and web site revenue maximization)

Your opinion will be welcome, but -remember- this is beta-test. So, it is full of bugs, problems, issues and don’t come back and complain if your significant other dumps you because of it.

Note: Most (if not all) of the photo-related news here will be applied to YLovePhoto.com as soon as I feel free with this new web site.

A few glasses and bottles

Yves Roumazeilles — Fri, 10 Oct 2008 12:25:45 +0000

I found a few funny, interesting, or surprising glasses or vases that I wanted to share with you.

The first ones are coming with a request to drink responsibly:

A Cognac glass (Rikke Hagen)

Vote for your favorite Martini glass design

Simple galssware (Martin Žampach)

A Klein bottle is a mathematical form whose particularity is to have no difference between its inside and its outside (this is elementary topology):

Finally, here is a vase that may have some difficulty to hold its water (it’s made of books):

The dots make the disc

The rock band Soulwax created an album with a nice optical illusion for its cover. You will have a move and squint your eyes a little to fully perceive the effect.

Anatomy of an illusion

Yves Roumazeilles — Tue, 19 Aug 2008 10:35:23 +0000

All the details about a simple optical illusion and what we can learn from it about the inner workings of the human brain.

Sun and shadows

Yves Roumazeilles — Wed, 13 Aug 2008 11:45:38 +0000

Where are the shadows? Where is the sun? This simple optical illusion could let you think that MC Escher did not survived to 2008.

Is it me? Is it you?

Do you see me?

I see you.

Slanted life

Look closely. The word LIFE is not as slanted as you’d think at first.

I love Paris illusion

If you read “I love Paris in the springtime”, read again.

Teach or Learn? Simply the illusion of a difference

Yves Roumazeilles — Wed, 09 Jul 2008 11:45:15 +0000

On the one side “Teach”, on the other “Learn”. Is it all simply an illusion? Ask teachers and students.

No sex, no eyes

Will you be able to read the text? Maybe you do not have perfectly good eyes and you should blink a little.
