World’s Largest Cylindrical Aquarium

‘Scuba diving in Germany’ isn’t usually penned into many tourists’ to-do lists — for obvious reasons — but at the Radisson Blu Hotel in Berlin this far-fetched idea becomes a reality with their towering Aquadom aquarium. A massive construction that looks like it came straight out of a James Bond movie, this incredible aquarium reaches 82-feet high and sits in the heart of the hotel’s lobby atrium. While guests can’t actually go for a dive in the Aquadom, they can enjoy the thrill of riding up … Continue reading

Can smells travel through a liquid?

Yes they can, they can also travel through solids as you might have noticed with some plastic packaging. Smells move around by the movement of what’s called aroma molecules and there are two main differences between the movement of these molecules in air and their movement in liquids or solids. The differences are the concentration of the molecules and the speed at which they travel through a medium. For example – in water, the concentration may be very low as … Continue reading

See a magnetic paradox in action!

Rare earth magnets are special kinds of magnets, and they behave in a very strange way when exposed to metals — especially copper. The faster they go, the more they slow down. Find out why, and take a look at people trying to force a slow-motion magnet to go fast. Many people have played around with a magnet, but it’s tougher to get your hands on a rare earth magnet. Rare earth magnets are made from rare earth elements. These … Continue reading

Sonic screwdriver tightens up fundamental physics

When the scriptwriters for Doctor Who imagined a futuristic device, they came up with the Sonic Screwdriver. Now a team of physicists at the University of Dundee have taken equipment designed for MRI-guided focused ultrasound surgery and demonstrated a real Sonic Screwdriver – lifting and spinning a free-floating 10 cm diameter rubber disk with an ultrasound beam. The Dundee researchers used energy from an ultrasound array to form a beam that can both carry momentum to push away an object … Continue reading

New motor can cut space exploration costs

A European team of researchers led by the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland has developed a prototype of a new, ultra-compact motor that will enable small satellites to journey beyond Earth’s orbit. The objective of this new motor is to make space exploration less expensive.  The compact motor weights only a few hundred grams and is specifically designed to propel small satellites, weighing from 1 to 100 kilograms. The conventional thruster can change orbit around our planet … Continue reading
