Researchers have investigated whether the perception of time changes with age, and if so, how, and why we perceive the passage of time differently. While we can argue why one summer may appear longer than the other and how the perception of time can compress and dilate durations depending on various factors, we can easily set up an experiment to gain more insights. Add more plates. Raise cannon balls. The book also describes the act of Heros, Bavarian heavy juggler; has a full page picture of a Chinese girl spinning two plates on sticks; and a short description of some Japanese foot jugglers. Second: a little nifty that could make a swell encore stunt for a comedy act. Bob Blau reports catching the act of Belmont Bros. Astronomers have been left stunned by a perfectly spherical explosion produced by a collision between two neutron stars 140 million light-years from Earth. And astronomers just don't know why. Scientists have advanced in discovering how to use ripples in space-time known as gravitational waves to peer back to the beginning of everything we know.

The researchers say they can better understand the state of the cosmos shortly after the Big Bang by learning how these ripples in the fabric of the universe flow through planets and the gas between the galaxies. The researchers just did that. The impact of human activity on the Earth system could result in unpredictable chaos from which there is no return, physicists have calculated. A finite amount of human activity could result in a Hothouse Earth from which there is no return. The electric version uses a bit of thread twisting round a biro refill pushed onto a motor shaft & rubber band return spring. This hat (which looks a bit like a fedora) is next season's must-have fashion item, able to be tiled across a plane to create patterns that never repeat. You'll have to experiment with the proper length of thread as well as the flipping of hat up from head. The hat was first identified by non-professional mathematician and "shape hobbyist" David Smith from the UK. Known as a kilanova, the enormous radioactive fireball was first detected in 2017 and is currently being analyzed by multiple teams of scientists, yet the latest revelation about its shape challenges our most fundamental assumptions about these cataclysmic events.

Bosons form one of the two fundamental classes of subatomic particle, the other being fermions. Subatomic particles can be separated into two categories: fermions and bosons. The primary differences between the two are how they spin and how they interact with each other. Yet, unlike the cue ball, a particle's spin can never speed up or slow down Ð rather, it's always confined to a set value. They set aside three age groups, 4-5, 9-10, and 18 years and older, and made them watch two videos, 1 minute each. Two identical fermions cannot occupy the same space at the same time. If it were large enough to have volume, the negative charge spread throughout that space would push on itself, billiard cue thread types tearing the electron apart. As envisioned by Albert Einstein and his collaborators in 1935, quantum objects can be mysteriously correlated even if they are separated by large distances. This past December, the physics Nobel Prize was awarded for the experimental confirmation of a quantum phenomenon known for more than 80 years: entanglement. It's not only more interesting but it is also easier to make because you don't need the wherewithall to cut & bend wire.

In practice this is quite difficult, and you need something sharp to make the holes. Many look at those experiments and conclude that they challenge "locality" Ð the intuition that distant objects need a physical mediator to interact. For the better part of a century, physicists have wrestled with the results of experiments that suggest the smallest pieces of reality don't look or behave anything like objects in our everyday lives. This new, third pattern is a moir, and it's between this type of overlapping arrangement of lattices of tungsten diselenide and tungsten disulfide where physicists found some interesting material behaviors. Using a theory conceived to model superconductivity, a team of physicists showed that, after a certain point, we will not be able to restore equilibrium to Earth's climate. Tom Breen says in reply to our article on audience participation, " We have been using the audience participation idea now for about four years and it really does go over nicely. We were playing at Alpine Village in Cleveland and one night went over extra well and Herman Pirchener who is M.C. as well as owner of the place insisted on an encore. So we asked the audience if they would like to see Herman try to Juggle. The new gag went over well and we kept it in after that. December 15th Collier's breaks the story on Lew Folds. The article is replete with errors. It is too bad the article wasn't written better because such publicity on a national scale has been scarce and should be valuable to all Jugglers by increasing public interest in the art. Larry Weeks types, "While en route to New York from Oakland, Calif., the train stopped in Chicago for four hours, so after buying a paper and finding The Five Willys listed at the Oriental, taxied right over, and spent a very pleasant couple of hours with them.
