V838 Monoceroti Expansion (Hubble)

It wasn’t anything interesting until it happened but the star V838 Monoceroti, which had simply sat in obscurity, flared up in 2002 to become 600,000 more luminous than our own Sun. It didn’t take long for the star to fade back into the darkness but the Hubble Space Telescope managed to get quite a few pictures of it during its active phase.

In this series of images you can see how the star’s outer layers were first expelled and then cut away by the powerful radiation from the star. The event was made even more interesting by the fact that a “light echo” was seen. During the expansion the object appeared to expand faster than the speed of light – the effect was however merely an astronomical optical illusion.

Let’s forget optical illusions for a moment. I’d like to dream. But illusions come back immediately, thanks to Eugen Erhan.

Put some fluorescent dye in water, let water droplets go and synchronize a stroboscopic light. You can get anyhting you want and it looks like magic.

One very cool optical illusion of a fade to black… and white.

And there’s another one very similar but with a different image: a waterfall.

Graphic artist and painter MC Escher produced a few very interesting paintings and engravings. But today, I give you the opportunity to see it differently. Bring on the video!

In the year 1956, “the Dutch graphic artist M.C. Escher made an unusual lithograph with the title ‘Print Gallery’. It shows a young man viewing a print in an exhibition gallery. Amongst the buildings depicted on the print, he sees paradoxically the very same gallery that he is standing in.”

The term was coined by the poet and columnist Nico Scheepmaker at the end of the 1970s. It is named after Droste, a Dutch brand of cocoa, whose box has a picture of a nurse carrying a serving tray with a cup of hot chocolate and a box of the same brand of cocoa.

You will find the following image and much more at AlgebraOfLife.

Straight lines are actually really parallels.

It’s your brain trying to convince you they’re not.

“You’ve got to love those coins!” Do you believe that I could tell you so? Surely not. Even better, you can be surprised to learn that I found that in a web site about design and arts (Baekdal.com). And it is defintely a great design for something as old as coins.

The new UK coins have been designed to be elegantly assembled in a single pattern:

It took all the art of bbzippo, some Lego bricks and some Photoshop editing, too.

If you go to the web site setup by Jatec-LLC, disappearing-car-door.com, you will see a revolutionary kind of sliding door for your car.

But is it real or fake?

Every purple square seems twisted. And is not.

Some people have been telling me: “You blog! That must take a lot of time and you must be there each and every day”.

Don’t worry, I may post something on Roumazeilles.net every day, but it does not mean that I am in front of the keyboard every day. Far from it. I am using one small advantage of WordPress (the software package supporting my web site). I can write posts and schedule them for future publication.

That way, I have no limit to my inspiration. For example, I have currently scheduled weekly posts about optical illusions for the coming 6 months, a full week of feline-related news (daily posts next week), a full week of daily videos titled “when XXXXX get bored” in a couple of months.

Everything is moving if you stare at this optical illusion.
