So fascinating, how certain folks suddenly care about "historical accuracy" in fiction when the Black people show up.

So I have a funny story about Governor General Jules Leger. I was working in the gardens on the grounds as a summer student in 1972 (might have been 1973, I can't quite remember, but it was the first year that women were hired as labourers by the NCC).1/

One of the things that we had to do was rake The pebble gravel on the paths and that was my task this particular day. I was out raking when I saw a Columbo type man dressed in a fedora and a crumpled raincoat approach me.2/

At that time the grounds were open to the public so it wasn't particularly surprising to have someone wander up and we chatted. I realized that he had recently had a stroke and that his English, while fluent, was a little slow. 3/

Anyway, we had a very nice chat and the next time I saw him in the garden, I showed him some baby rabbits that had a nest in the front rotundra. He thought they were pretty adorable.4/

I was able to pick one up for him to hold, but it was difficult for him because one of his hands was quite paralyzed. Anyway, he thought this was very lovely and our regular chats continued.4/

Today is Jayanti of Satyendranath Bose or more popularly known as S.N.Bose. Well known for the Bose-Einstein condensate theory. And also a class of particles called Bosons named after him by Paul Dirac. One of the great scientists of modern era.

But then again to call S.N.Bose just a scientist, would be akin to calling Leonardo Da Vinci a mere painter. Much like his other namesake and contemporary, J.C.Bose, he was a polymath, equally adept in music, literature,mineralogy.

The multi facted genius was born on January 1, 1894 in a middle class Kolkata family, his father Surendranath Bose, an accountant in the East India Railway Company. The only son in a family that had six daughters after him.

Bought up by his mother Amodini Devi, he later joined the New Indian School in the Goabagan neigbhorhood of Kolkata. Seeing his skills at mathematics, his father encouraged him more by giving problems to solve.

Joining the prestigious Hindu School in 1907 at the age of 13, he soon got recognition as an oustanding student in maths and science. His maths teacher, believed he could be the next Pierre Laplace.

The Story of how Mary Slessor Stopped the killing of Twins but sadly died of Fever.

All you need to know

Retweet to educate someone

Killing new-born twins was common practice in the 19th century among the Ibibio people of Nigeria, but one Scotswoman went to great lengths to put an end to this.

Aberdeen-born Mary Slessor was one of the few missionaries in Africa who learnt the local language, adapted to the native customs and environment and gained the trust of the locals in order to make a truly positive impact.

Her father, a shoe-maker from Buchan, became incapacitated by alcoholism and Mary more or less became the breadwinner for the family.

From the age of 11, she worked as a ‘half-timer’ mill girl in the Baxter Brothers and Co Ltd, spending half the day at a school provided by the mill owners and the other half working for the company

Why are loops called "loops"?

Before addressing the question in the title tweet, let me first back up to the origin of the term "quasigroup". The first use of the term was by Ruth Moufang in 1935 in her study of the multiplicative structure of the octonions.

Moufang defined "quasigroup" in a much narrower sense than we do now. The details are not part of this story, so I'll skip them. What she called quasigroups we now call Moufang loops in her honor.

The current definition of quasigroup - a set with binary op * s.t. for all a,b, the equations a*x=b, y*a=b have unique solutions x,y - is due to Hausmann & Ore (1937), in the same paper where they introduced the "other" meaning of "groupoid": a set with a binary operation

It was A.A. Albert (1943) who introduced the term "loop" for a quasigroup with identity element. In his words, "It will be very convenient to have a special name for such quasigroups..." (p.510)
