Flying bicycle survives unveiling without horrible crash Is it a bike? Is it a plane? Three Czech companies have teamed up to make a prototype of an flying bicycle that successfully took off Wednesday inside an exhibition hall in Prague and landed safely after a remote-controlled, five-minute flight.
Looking like a heavy mountain bike, it weighs 95 kilograms. It has two battery-power propellers in the front, two in the back and one each on the sides. A dummy rode in the saddle. (Photo: MICHAL CIZEK/AFP/Getty Images)
Our first meeting will be held on Tuesday, June 18 at 7:30 PM at Madison Square Park (weather permitting). Please enter the park at 5th Avenue and 26th Street. I’ll bring some sort of sign and set up near that entrance.
If you can bring a blanket or towel to sit on, please do. If you would like…
Next Tuesday night, there’s a group discussing IJ in NYC and I’m going to try to be there.
Me too! This book has been on my re-read stack for ages. Maybe its finally time to dive in.
Before there was life on land, trilobites roamed the Earth’s oceans. These extinct marine arthropods first evolved about 520 million years ago, during the Cambrian Period, when the planet was mostly covered in water.
Cambrian trilobites shared the shallow seas with jellyfish and primitive mollusks such as snails and clams, along with annelid worms and sponges. Their shells were made of the mineral calcite, like clam- or crabshells and they were also the earliest known life forms with compound eyes. Some trilobites even had eyes on stalks, perhaps for peering above the sediment in the waters where they lived.
Amazing resonance experiment with salt Using a vibrating metal plate connected to tone generator, Scientist Bruss Pup performs scientific magic by seemingly controlling and manipulating grains of salt to dance in specific patterns.
Wow…if that is happening with just salt, imagine how that affects our bodies when we listen to music…
