Krononaut Moon 🌕 2025 Mar 14

The #KrononautMoon Project is an ongoing series of community experiments to contact #TimeTravelers — as "in-person", but more likely via #quantum #signal. The next attempt is coming up soon on 14 Mar 2025 — under the #TotalLunarEclipse — wherever you are. These outreaches are sometimes referred to as "landing receptions", but call them or redesign them however you like. Following is a brief, all-true #chronology of such #events, going back 40+ years. The excerpt is from our detailed #article on Medium.com.

❛❛ #Future #intelligences would have the necessary transport #technology that is not yet existent in our #world. To date, there have been 5 recorded attempts of this method, with the most famous one devised by the late #theoretical #physicist #StephenHawking, in #Cambridge #UK on 2009 Jun 28.

Hawking referred to his get-together as a “reception”—what we now think of as a version type 1.0. His champagne toast to “tourists from the future” was, by no means, not the first of the prototypes, however, because it was staged years after 3 similar experimental attempts — stationed in different #countries and unrelated to each other. The professor’s cheeky soirée occurred four years after a rollicking party that was thrown for “Inhabitants of the Future” at Forrest Place, #Perth #AU, on 2005 Mar 31. Then, a few months later, an equally festive #TimeTraveler #Convention was hosted at #MIT — The #Massachusetts Institute of Technology, #Cambridge #MA #US, on 2005 May 07. These elaborate productions were preceded by a full two decades, back when a group identifying itself as the #Krononauts assembled in #Baltimore #MD #US (alt. spelling: #Chrononauts). That seminal event, which was covered by a #NewYorkTimes reporter, happened at a downtown #bookstore, under the light of a #FullMoon, and a multi-planetary #syzygy, on 1982 Mar 09.

More recently, in the spring of 2023, a dogged #podcaster for TheLastArchive.com and Pushkin.fm, published a riveting and droll #audio recounting of Baltimore’s Krononauts gathering, and then gave the concept a uniquely personal #experimental spin, noting the time and #GPS #coordinates. The effort successfully demonstrated that a single individual can attempt extra-temporal #contact on one’s own, equipped with little more than a #public #library #bench, and can meaningfully contribute to the corpus of #Community #Time #Travel #Research. ❜❜

On 2025 Mar 14, join your #friends, fellow #Mastodonians, and #TimeTravelers for an evening of #peace, #love, and #cosmic #tranquility, wherever you are.

Bonus #ArtAdventCalendar day 17 Happy birthday to Gabrielle Émilie Le Tonnelier de Breteuil, Marquise du Châtelet (1706-1749), a natural philosopher, #mathematician and #physicist, shown here in my #linocut portrait with #diagrams from her ‘Principes Mathématiques de la Philosophie Naturelle’, a two-volume translation and commentary of Newton’s ‘Principia’, published in 1759 in French in Paris.🧵

Did you know that #invisibility cloaks are #real?

From the 2nd c's Cap of Hades to #Marvel 's Invisible Woman, magic that renders one #invisible is a common theme in #mythology & #scifi.

In 2006, #theoretical #physicist John Pendry figured out that light could be bent around an object so that it renders it invisible.
This led to many advancements in metamaterial science, known as 'metamaterial cloaking'.

I've enjoyed this talk by Pendry: youtube.com/watch?v=VO6IrynhjK [start: 4:43min]

Happy birthday to #physicist Lise Meitner (1878-1968) who explained #nuclear #fission. She worked with chemists Hahn & Straßmann in 30s Berlin, investigating whether there were any stable elements beyond uranium. They discovered bombarding nucleus of U-235 with neutrons actually triggered it to fission, or break, into 2 nuclei of roughly half the size & some free neutrons! Hahn’s chemistry lead to startling discovery of barium,🧵

My linocut print of Lise Meitner holding her glasses in one hand, while leaning on the other, in silver ink. In red ink is a nuclear fission chain reaction shown with a single neutron (white ball with motion lines) emanating from her head towards a nucleus (conglomerate of red proton and white neutron balls) then an arrow to it fissioning (becoming split into two adjacent then two separate halves with extra free neutrons). These neutrons in turn all begin the same process with other nuclei and the chain reaction takes up the left side of the print next to Meitner.

When #physicist Lise Meitner (1878-1968) explained #nuclear #fission she understood nothing was “lost” (today’s #SciArtSeptember prompt) despite the missing mass after the reaction. She worked with chemists Hahn & Straßmann in 30s Berlin, investigating elements beyond uranium. They found bombarding nuclei of U-235 with neutrons actually triggered it to fission, or break, into 2 nuclei of roughly half the size & some free neutrons! 🧵1/n

For the #SciArtSeptember prompt mirror: #physicist Chien-shiung Wu (1912-1997), who came up with a truly beautiful experiment to test whether the weak force conserves parity (whether beta decay would be the same if reflected in the mirror)! I show Wu in her lab & a schematic diagram of her experiment. On the right I show her reflection, as in the mirror, & the mirror reflection of the 🧵1/n

The top is labeled S, the bottom is labeled N and the middle is wrapped in wire drawn as a circuit diagram schematic with parallel lines to indicate a power source and left arrow on top wire, right arrow on bottom. Between the poles of the magnet is a big blue dot to designate Cobalt-60 with many tiny dots as beta-decay electrons, the majority going downwards to N pole. On the right, everything is flipping except most electrons go upwards (and and N and S poles are flipped).

Despite articles such as this one in the Guardian highlighting the sexism on #Wikipedia and specifically highlighting how Nobel prize winning #physicist, Donna Strickland, wasn't considered notable enough to have an entry in Wikipedia, a (white, male) editor decided to remove all reference to these facts from her article.

Which is precisely why I added her to my watchlist some time ago.

Happy birthday to #physicist Harriet Brooks (1876 - 1933) who discovered atomic recoil, Radon & recognized radioactive elements could undergo chains of transmutations into a series of new elements. #nuclear #physics⁠
⁠
She was Rutherford’s 1st grad student at McGill. After publishing her results in 1899 she completed her MSc in 1901 on "Damping of Electrical Oscillations," before embarking on #radioactivity research.⁠

My 9.25" x 12.5" linocut portrait of physicist Harriet Brooks (1876 - 1933) in a gradient of turquoise to green, shows her and her discovery of atomic recoil in gold (Radon gives off an alpha particle and daughter nucleus goes in opposite direction). A series of diagrams at the bottom shows how the Rutherford research group understood chains of radioactive active transmutations at the time.

Happy birthday to #physicist James Clerk Maxwell (1831-1879)! He dreamt up his demon to deal with the very odd 2nd Law of Thermodynamics (which is not a law like others, and can not be derived from first priciples). It states that two bodies of different temperature brought together in a closed system will reach thermal equilibrium; or, you cannot use a cold thing to heat a hot thing; 🧵1/

Linocut print, 8”x10” on white washi paper, showing Maxwell’s demon in blue in a circle in the centre surrounded by red with the words “Maxwell’s” above and “Demon” below, arcing around the circle. My nimble-fingered demon resembles Maxwell, but with horns, extra-long fingers and enormous eyes to see and track particles and is using the cold blue region to warm the hot red region. In the blue region there are random slow moving particles denoted by dots with two tails. Carved into the red area are fast moving particles denoted by dots with three longer tail lines.

This is a #linocut of French #mathematician & #physicist Joseph Fourier (1768-1830) remembered for his work on Fourier series, Fourier transforms, Fourier’s law of conduction, Fourier analysis & harmonic analysis & their use to solve heat transfer problems & credited with proposing the greenhouse effect as early as 1824.

Being a commoner he could not seek a commission in the scientific corps of the army but took a military lectureship in #math. 🧵1/n

My linocut print on 11”x14” white washi paper had one large section of a circle and several varied smaller overlapping circles in tints and shades of pale orange to pale golden yellow-orange. Fourier is printed in blue ink on top of these orange circles and dressed in 18th century garb. A red sinusoidal function is printed on top such that his head finds within a crest and the throughs to either side frame him. There’s are smaller sinusoids in green, pale blue and yellow on either side of his neck. The sum of these functions frames him in a purple line.

@gutenberg_org Yes, #HappyBirthday 🎂 to #physicist #MaxPlanck , who in 1900 was the founder of the #QuantumTheory - of #energy.

But a century earlier, using empirical data from 18th century #chemistry , #chemist #JohnDalton correctly postulated what could be called the #QuantumTheory of mass when he resurrected and modernized the #AncientGreek #philosophy of #Atomism attributed to #Democritus. #Histodons

Born on this day: #physicist J. R. Oppenheimer (1904-1967). While best remembered for his role in the Manhattan Project, he was a giant of 20th century theoretical physics, nominated for a Nobel 3 times. ⁠

In 1927 he & Max Born greatly simplified how we predict electrons behaviour within atoms. The Born-Oppenheimer or adiabatic approximation is based on the observation that electrons are 1000s times lighter than nuclei, 🧵1/n
