The chain fountain phenomenon, also known as the self-siphoning beads, Mould effect, or Newton beads is a physical phenomenon observed with a chain placed inside a jar. One end of the chain is pulled from the jar and is allowed to fall under the influence of gravity .
Steve Mould (born 5 October 1978) is a British educational YouTuber, author, [2] and science presenter who is most notable for making science-related educational videos on his YouTube channel. Early life
[6] [7] This experiment not only had effects in biology, figuring out a way in which a brainless organism seems to make decisions, but it affects philosophy by changing the understanding of intelligence. [8] Using this research, Toshiyuki Nakagaki placed a slime mold in a recreation of Tokyo. The slime mimicked the Tokyo railway system without ...
The objectives of experimental mathematics are "to generate understanding and insight; to generate and confirm or confront conjectures; and generally to make mathematics more tangible, lively and fun for both the professional researcher and the novice". [5] The uses of experimental mathematics have been defined as follows: [6]
He also weighed castings per unit area per year, then worked out how thick a layer castings would make, compared with rates of sinking. Additionally, he worked out casting weight per worm per year. Darwin's experiments included measuring the speed with which stones slowly settle into the earth.
Alexander Fleming demonstrates that the zone of inhibition around a growth of penicillin mould on a culture dish of bacteria is caused by a diffusible substance secreted by the mould (1928). Frederick Griffith demonstrates (Griffith's experiment) that living cells can be transformed via a transforming principle, later discovered to be DNA (1928).
For conservation of number, the task designed to test children involves a set of several sticks or round counters. These counters (usually 6 for a 6-year-old) are placed into two parallel, horizontal lines that are the same length. Then the researcher spreads out the counters in one of the lines, to make that line longer than the other.
Physarum polycephalum, an acellular [1] slime mold or myxomycete popularly known as "the blob", [2] is a protist with diverse cellular forms and broad geographic distribution. The “acellular” moniker derives from the plasmodial stage of the life cycle : the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a ...
