Physics is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves. https://en.wikipedia.org/wiki/Physics

Signals
A signal is usually defined as:
- A signal is a function that represents the variation of a physical quantity with respect to any parameter (usually time or space) [with respect to at least one independent variable (time or space)]. https://www.youtube.com/watch?v=M0mx8S05v60 https://x-engineer.org/graduate-engineering/signals-systems/signal-processing/what-is-a-signal
- A signal is a function that conveys information about a phenomenon. https://en.wikipedia.org/wiki/Signal#Classification
In electronics, a signal is an electric current or electromagnetic field used to convey data from one place to another. The simplest form of signal is a direct current (DC) that is switched on and off; this is the principle by which the early telegraph worked. More complex signals consist of an alternating-current (AC) or electromagnetic carrier that contains one or more data streams. https://searchnetworking.techtarget.com/definition/signal
Sound, images and videos are also considered to be signals. https://en.wikipedia.org/wiki/Signal#Classification
It is not clear if a signal must be a function of time/space; or if it can be of any other parameter.
It is neither clear if the signal is the physical phenomenon (for example, the seismic wave) or the functional representation of the physical phenomenon (the seismogram).
Signal analysis - Signal processing
One of the applications of Mathematical analysis (Calculus in particular) is for Signal processing. When processing signals, such as audio, radio waves, light waves, seismic waves, and even images, Fourier analysis can isolate individual components of a compound waveform, concentrating them for easier detection or removal. A large family of signal processing techniques consists of Fourier-transforming a signal, manipulating the Fourier-transformed data in a simple way, and reversing the transformation. https://en.wikipedia.org/wiki/Mathematical_analysis#Signal_processing

- Seismic processing
- Time-frequency analysis in Seismic processing:
- A set of mathematical formulas used to convert a time function, such as a seismic trace, to a function in the frequency domain (Fourier analysis) and back (Fourier synthesis). The Fourier transform is used extensively in signal processing to design filters and remove coherent noise. Many filtering operations are performed in the frequency domain. The Fourier transform has applications in image analysis and in pattern recognition in geological systems. https://www.glossary.oilfield.slb.com/en/Terms/f/fourier_transform.aspx#:~:text=A%20set%20of%20mathematical%20formulas,and%20back%20(Fourier%20synthesis).&text=The%20Fourier%20transform%20is%20used,filters%20and%20remove%20coherent%20noise.

Detailed explanation of Einstein's article on the Brownian motion: https://www.youtube.com/watch?v=4XI5pk7P-Yo
Brownian Motion is the random movement displayed by microscopic particles suspended in fluids. It was name after the botanist Robert Brown, who in 1827, performed experiments where he observed pollen seeds suspended in water under the microscope. The tiny grains suspended in water make random zigzag motions. This motion never appeared to slow o stop.
in 1905, Einstein developed a mathematical model for brownian motion based on atomos. Einstein explained that the pollen grains were being moved by water molecules around them. Einstein even derived how big atomos should be based on how the brownian particles move.
Einstein's model was the first hard evidence that supported the existence of atoms.

The discoveries of Carbon Dioxide, Hydrogen, and Nitrogen
Joseph Black (16 April 1728 - 6 December 1799) was a Scottish physicist and chemist, known for his discoveries of magnesium and carbon dioxide. He found that limestone (calcium carbonate) could be heated or treated with acids to yield a gas he called "fixed air." He observed that the fixed air was denser than air and supported neither flame nor animal life. https://en.wikipedia.org/wiki/Joseph_Black | |

Hennig Brand discovers phosphorus, Germany Hennig Brand (1630 - 1692 or 1710), Hamburg, Germany. Hennig Brand was a German alchemist. Like other alchemists of the time, Brand searched for the "philosopher's stone", a substance which supposedly transformed base metals (like lead) into gold. During his searches for developing a method of obtaining gold, around 1669 he heated residues from boiled-down urine on his furnace until the retort was red hot, where all of a sudden glowing fumes filled it and liquid dripped out, bursting into flames. He could catch the liquid in a jar and cover it, where it solidified and continued to give off a pale-green glow. What he collected was phosphorus, which he named from the Greek word for "light-bearing" or "light-bearer." https://en.wikipedia.org/wiki/Hennig_Brand This is how one of the first elements, phosphorus (o el primero no estoy seguro) fue descubierto.
This documentary seems to be nice. It explains how elements were discovered and classified and how the total number of elements was defined. In the second part of the video, the creation of the atomic bomb is explained. |
