Long Study Day At The Library! There Was A Lot Of Snacks Since It’s Finals Week But Getting A Spot

Dolphin Head Nebula taken by Ben Brown on February 23 2024

The Dolphin Head Nebula, Sh 2-308, is an emission nebula caused by the Wolf-Rayet star EZ Canis Majoris. WR stars have completed fusion of hydrogen and are now fusing heavier elements such as helium and carbon. They have unique emission spectrums for this reason, with no hydrogen emission lines.

The temperature of WR stars is much higher than typical stars, reaching 20,000 K to 210,000 K. WR stars are some of the most luminous stars due to their high temperatures, but most of their output is in the ultraviolet spectrum, meaning we can't see it with the naked eye.

This UV radiation ionizes the gas around it, leading to the emission nebula you can see in the photograph.

“the best revenge is massive success,"

Pretty winter sunset but I’m stuck inside 🌅 Just cleaned my room though so I don’t mind that much.

3rd picture is my desk— should I put something on the wall? I don’t want to drill anything in.

Today was pretty frustrating for a variety of reasons, so I didn’t think I would get much done today but then I hopped on to Tumblr and saw a bunch of people’s study posts so I guess I’m trying this again.

- Study for math test

- Work on research program applications

- Upload a new software onto my computer

Good luck 👍

today is a study day (fortunately or regrettably depending on your perspective). this problem set is really cool and i actually like learning about circuits, which i didn’t expect.

- circuits problem set (88 mins)

- circuits quiz (39 mins)

- advanced circuits lecture

i’m REALLY behind in my course and i need to catch up by the time school starts again so i probably have another 4 hrs of work minimum. it’s finally feeling like crunch time lol

tonight’s setup 😊 hopefully I go to bed at a reasonable time. I still have TWO lab reports to finish though.

I thought my math homework was going to be chill because it was just two problems but tell me why I open it and it’s part a-p 😭

We went to the local observatory tonight but when we got there, there was a HUGE line of people. Whoops. It’s was still really pretty and we got to see an amazing view of the stars.

These are my attempts to take a picture of the sky with my phone but they didn’t turn out very well. I don’t even remember what I was trying to photograph. Next time, I’ll try to bring an actual camera.

I think the brightest one in the left picture might be Jupiter???? lol 🥲

first day of winter break! i woke up early this morning for a meeting and it was still dark. then i witnessed one of the most beautiful sunrises i have ever seen. my entire room was orange

so glad finals are over :)

15/01/25 - 16/02/25

Forgetting to make this posts hehe- So much has happened :3

Had my music exam (it was funny lol -like fr). The examiner was the advocate of High Court! 💀 (I got to know it only after coming out of the exam room) She told me to remember things more (I forgot many things huff) for next year and not to get nervous (I was offered water THAT'S HOW MUCH I GOT NERVOUS).

Organised the farewell of our seniors <3 (can't believe that soon it'll be my last year of school).

Wore beautiful dresses in different events and took no photos alone. 🕶️ (WHYYYYY)

Gonna have my last classes of 11th tomorrow! Finals start from the 6th of March; yo girlie's locking in! :p

Currently, writing my chemistry practicals and computer science project (DUDE I HAVE TO WRITE 275 LINES OF CODE ON PAPER -ON PAPER).

Ancient Greek Women Mathematicians you didn't know about

Αίθρα - Aethra (10th - 9th century BC), daughter of the king of Troizina Pitthea and mother of Theseus, knew mathematics in another capacity unknown to many. So sacred to the beginnings of the most cerebral science, Aethra taught arithmetic to the children of Troizina, with that complex awe-inspiring method, since there was no zero… and the numbers were symbolically complex, as their symbols required many repetitions.

Πολυγνώτη - Polygnoti (7th - 6th century BC) The historian Lovon Argeios mentions Polygnotis as a companion and student of Thalis. A scholar of many geometric theorems, it is said in Vitruvius' testimony, that she contributed to the simplification of arithmetic symbols by introducing the principle of acrophony. She managed this by introducing alphabetic letters that corresponded to each in the initial letter of the name of the number. Thus, Δ, the initial of Δέκα (ΤΕΝ), represents the number 10. X, the initial of Χίλια (Thousand), represents the number 1000 etc. According to Vitruvius, Polygnoti formulated and first proved the proposition "Εν κύκλω η εν τω ημικυκλίω γωνία ορθή εστίν" - "In the circle the angle in the hemi-circle is right angle."

Θεμιστόκλεια - Themistoklia (6th century BC). Diogenes the Laertius scholar-writer mentions it as Αριστόκλεια - Aristoclia or Θεόκλεια - Theoclia. Pythagoras took most of his moral principles from the Delphic priestess Themistoclia, who at the same time introduced him to the principles of arithmetic and geometry. According to the philosopher Aristoxenos (4th century BC), Themistoclia taught mathematics to those of the visitors of Delphi who had the relevant appeal. Legend has it that Themistoclia decorated the altar of Apollo with geometric shapes. According to Aristoxenos, Pythagoras admired the knowledge and wisdom of Themistoclia, a fact that prompted him to accept women later in his School.

Μελίσσα - Melissa (6th century BC). Pupil of Pythagoras. She was involved in the construction of regular polygons. Lovon Argeios writes about an unknown work of hers: "Ο Κύκλος Φυσίν - η Μελίσσα - Των Εγγραφομένων Πολυγώνων Απάντων Εστί". (The title translates to "The circle is always the basis of the written polygons" or so.)

Τυμίχα - Tymicha (6th century BC). Thymiha, wife of Crotonian Millios, was (according to Diogenes Laertius) a Spartan, born in Croton. From a very early age, she became a member of the Pythagorean community. Iamblichus mentions a book about "friend numbers". After the destruction of the school by the Democrats of Croton, Tymicha took refuge in Syracuse. The tyrant of Syracuse, Dionysios, demanded that Tymicha reveal to him the secrets of the Pythagorean teaching for a great reward. She flatly refused and even cut her own tongue with her teeth and spat in Dionysius' face. This fact is reported by Hippobotus and Neanthis.

Βιτάλη - Vitali or Vistala (6th – 5th century BC). Vitali was the daughter of Damos and granddaughter of Pythagoras, and an expert in Pythagorean mathematics. Before Pythagoras died, he entrusted her with the "memoirs", that is, the philosophical texts of her father.

Πανδροσίων ή Πάνδροσος - Pandrosion or Pandrossos (4th century AD). Alexandrian geometer, probably a student of Pappos, who dedicates to her the third book of the "Synagogue". Pandrosion divides geometric problems into three categories:" Three genera are of the problems in Geometry and these, levels are called, and the other linear ones."

Πυθαΐς - Pythais (2nd century BC). Geometer, daughter of the mathematician Zenodoros.

Αξιόθεα - Axiothea (4th century BC). She is also a student, like Lasthenia, of Plato's academy. She came to Athens from the Peloponnesian city of Fliounda. She showed a special interest in mathematics and natural philosophy, and later taught these sciences in Corinth and Athens.

Περικτιόνη - Periktioni (5th century BC). Pythagorean philosopher, writer, and mathematician. Various sources identify her with Perictioni, Plato's mother and Critius' daughter. Plato owes his first acquaintance with mathematics and philosophy to Perictioni.

Διοτίμα - Diotima from Mantineia (6th-5th century BC). In Plato's "Symposium", Socrates refers to the Teacher of Diotima, a priestess in Mantineia, who was a Pythagorean and a connoisseur of Pythagorean numerology. According to Xenophon, Diotima had no difficulty in understanding the most complex geometric theorems.

Iamblichos, in his work "On Pythagorean Life", saved the names of Pythagorean women who were connoisseurs of Pythagorean philosophy and Pythagorean mathematics. We have already mentioned some of them. The rest:

Ρυνδακώ - Rynthako

Οκκελώ - Okkelo

Χειλωνίς - Chilonis

Κρατησίκλεια - Kratisiklia

Λασθένια - Lasthenia

Αβροτέλεια - Avrotelia

Εχεκράτεια - Ehekratia

Θεανώ - Theano

Τυρσηνίς - Tyrsinis

Πεισιρρόδη - Pisirrodi

Θεαδούσα - Theathousa

Βοιώ - Voio

Βαβέλυκα - Vavelyka

Κλεαίχμα - Cleaihma

Νισθαιαδούσα - Nistheathousa

Νικαρέτη - Nikareti from Corinth

There are so many women whose contribution to science remains hidden. We should strive to find out about more of them! For more information, check out the books of the Greek philologist, lecturer, and professor of ancient Greek history and language, Anna Tziropoulou-Eustathiou.
