So much worth to read of this thread. Thanks you so much, I will post mine in a couple of days that is worth read as well.

The Scientific Alphabet.

A is for argument, sometimes profound,
B for the bullshit that lies all around.
C is for light speed – a limit for all,
D for dimensions rolled up really small.
E is for energy; that you must know,
F for the future, towards which we go.
G is for general; a relative type,
H for Planck’s constant, h-bar and hype.
I is for infinite – everything’s in,
J is for joule and repetitive jinn.
K for kinetic – an energy kind,
L for the ludicrous concepts we find.
M is a theory all tied up in strings,
N is a number that covers all things.
O for opinion; a person’s belief,
P for momentum, p-brane and relief.
Q is for quantum and quark – sometimes strange,
R is for radius and also for range.
S is for science, to which we stay close,
T is for time and for theories verbose.
U for the Universe in which we all sit,
V for the vacuum; full of weird sh1t.
W for wisdom – we can’t get enough,
X for the X-rays that see through our bluff.
Y is for Yang, who with Mills makes a pair;
Z is for zero, that’s really not there.

The Forum’s guardians of “Faith and morals” changed the original to:

sh1t.

Isn’t this hypocrisy? If using a word is offensive, surely using it, while pretending that one is not, is both offensive and insulting

Just a thought.

Isotope
Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom. The term isotope is formed from the Greek roots isos and topos, meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.

Sorry if I disrupted the  concatenation of this thread, it's something I do well.

I is for Inselberg.

This is a landform in which erosion gives rise to an isolated hill rising abruptly from a plain.

Overview
Jasper, an aggregate of microgranular quartz and/or chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron inclusions. The mineral aggregate breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9.

I'd like to mention James Joule as the instigator of one of the most profound concepts of physics, the mechanical equivalent of heat, which turns up in pretty well every aspect of engineering from lift-off to re-entry and replaces rules of thumb with a single precise value that saves lives.

Kryptonite

From Wikipedia, the free encyclopedia

Kryptonite is a fictional  REAL material that appears primarily in Superman stories. In its most well-known form, it is a green, crystalline material originating from Superman's home world of Krypton, that emits a peculiar radiation that weakens Superman, but is generally harmless to humans when exposed to it in short term. There are other varieties of kryptonite such as red and gold kryptonite which have different but still generally negative effects on Superman. Due to Superman's popularity kryptonite has become a byword for an extraordinary exploitable weakness, synonymous with "Achilles' heel".

Nano- (symbol n) is a unit prefix meaning "one billionth". Used primarily with the metric system, this prefix denotes a factor of 10−9[/size] or 0.000000001. It is frequently encountered in science and electronics for prefixing units of time and length.[/color]

                Orion

Orion is a prominent constellation located on the celestial equator and visible throughout the world. It is one of the most conspicuous[1] and recognizable constellations in the night sky.[2] It is named after Orion, a hunter in Greek mythology. Its brightest stars are blue-white Rigel (Beta Orionis) and red Betelgeuse (Alpha Orionis).

Planck Length


In physics the Planck length, denoted is a unit of that is the distance light in a perfect vacuum travels in one unit of Planck time. It is also the reduced Compton wavelengthof a particle with Planck mass It is equal to 1.616255(18)×10 m.It is a n the system of Planck units, developed by physicist Max Planck[. The Planck length can be defined from three fundamental physical constants: the speed of light[ in a vacuum[, the Planck constant[nd thegravitational constant[. It is the smallest distance about which current, experimentally corroborated, models of physics can make meaningful statements. At such small distances, the conventional laws of macro-physics no longer apply, and even relativistic physics requires special treatment.

Quark


Any of the hypothetical particles with spin 1/2, baryon number 1/3, and electric charge 1/3 or −2/3 that, together with their antiparticles, are believed to constitute all the elementary particles classed as baryons and mesons; they are distinguished by their flavors, designated as up (u), down (d), strange (s), charm (c), bottom or beauty (b), and top or truth (t), and their colors, red, green, and blue.

Relation and Rovelli

Most physical qualities seem to be Relations. Galilean Relativity demonstrated that position and velocity were Relative to a reference frame. Einstein showed that even time and mass are Relations and not absolute properties. Most importantly, Carlo Rovelli showed that ontology, or existence itself, can be a Relation by introducing the RQM interpretation of quantum mechanics.

Time now for some R & R

Here’s one for the letter M
Marie Curie
On November 7, 1867, Marie Curie was born in Warsaw, Poland, the daughter of a secondary school teacher. Her father provided her with some scientific training as well as a general education in local schools. She became active in a student revolutionary movement and decided to leave Warsaw, which was then under Russian control, for Cracow, which was then under Austrian power. She moved to Paris in 1891 to further her studies at the Sorbonne, where she earned Licenciateships in Physics and Mathematical Sciences. In 1894, she met Pierre Curie, a professor at the School of Physics, and married the following year. She replaced her husband as Head of the Physics Laboratory at the Sorbonne, earned her Doctor of Science degree in 1903, and after Pierre Curie's sad death in 1906, and she became the first woman to hold the position of Professor of General Physics in the Faculty of Sciences. She was also named Director of the Curie Laboratory at the University of Paris' Radium Institute, formed in 1914. Her early research, along with that of her husband, was often carried out under challenging circumstances, with inadequate laboratory facilities and both of them having to teach to make a living. The Curies' excellent research and analyses were motivated by Henri Becquerel's discovery of radioactivity in 1896, which led to the isolation of polonium, called after Marie's birth country, and radium. Curie passionately championed the use of radium to alleviate pain throughout her life, and during World War I, she personally devoted herself to this remedial activity, assisted by her daughter, Irene. She maintained her passion for science throughout her life and contributed significantly to the establishment of a radiation laboratory in her hometown.

Does anyone know the best cure for the hangover from hell?. Right know my head is thumping like the 1812 overture being played at full tilt lol. I knew i shouldnt have had that last pint.

Umbra is shadow, or a dark tone or area. An example of an umbra is the shadow beyond a streetlight. An example of an umbra is the darkest part of the shadow cast by an eclipse.

The mineraloid opal is amorphous SiO2·nH2O, hydrated silicon dioxide.The water content is usually between three and ten percent, but can be as high as 20%.Opal ranges from clear through white, gray, red, yellow, green, shore, blue, magenta, brown, and black.

Of these hues, red and black are the most rare and dear, whereas white and green are the most common; these are a function of growth size into the red and infrared wavelengths see precious opal.Common opal is truly amorphous, but precious opal does have a structural element.

Hi.
   That's a good first post @robertryan .   Hi and welcome.
Best Wishes.
