Keeping in the swing of things … ChatGPT is open currently. Me: What is a Bravais pendulum?
Chat GPT repeated the crystallography statement David shared earlier. So far the percentages are still weighed against the facts. Being told something is incorrect and being provided accurate information has so far failed to correct its response. Asking ‘What are the different types of pendulums and how do they differ?’ generated a list of 5: Simple pendulum: This is a mass hanging from a string or rod that swings back and forth under the influence of gravity. The motion of a simple pendulum is determined by its length and the strength of the gravitational field. Compound pendulum: This is a pendulum that has a rigid body, such as a rod or a solid sphere, that swings about a pivot point. The motion of a compound pendulum is determined by its mass, length, and the distribution of mass around the pivot point. Foucault pendulum: This is a pendulum designed to demonstrate the Earth's rotation by swinging in a plane that appears to rotate over time. The pendulum's plane of swing changes continuously because of the rotation of the Earth, which causes the pendulum to trace out a curve in space. Physical pendulum: This is a pendulum that consists of a rigid body swinging about a pivot point, such as a weight on a lever or a rotating wheel. The motion of a physical pendulum is determined by its moment of inertia and the strength of the gravitational field. Torsion pendulum: This is a pendulum in which a small weight is suspended from a thin wire or rod, and the motion of the pendulum is caused by the twisting and untwisting of the wire or rod. The motion of a torsion pendulum is determined by the tension in the wire or rod, the angle of twist, and the mass of the weight. Each type of pendulum has its own unique properties and is used for different purposes, ranging from demonstrating the principles of physics to making precise measurements in scientific experiments. Poor old Bravais failed to make the cut, just not unique enough it seems. Asked about the utility of pendulums for dowsing came back with a safe, better off using ‘established methods, such as drilling, remote sensing, and geophysical surveys…’ Regards Nicholas English Sent from A phone |-) There will always be a market for tin foil hats while we have electricity ... do we have electricity?! > On 4 Feb 2023, at 5:06 pm, David <[email protected]> wrote: > > We now know. > > Two readers of this thread have emailed me with ChatGPT's responses to their > their own re-presentation of Bernard's query.
