And since today is International Day of Women and Girls in Science, let's highlight a few of them - just a few women among thousands of others who helped shape the world we live in today.

Thread.

Dorothy Hodgkin discovered the structure of insulin after 36 years of work.

"I was captured for life by chemistry and by crystals."

"It seemed discreditable to Great Britain that all her daughters who desired a University education should be driven abroad to seek it."

Mary Anning is credited with the discovery of several dinosaur specimens that assisted in the early development of paleontology.

“It is large and heavy but… it is the first and only one discovered in Europe.”
Caroline Herschel was the first woman to discover a comet (she would spot seven more). She also detected three nebulae, in 1783.
Flossie Wong-Staal was the first scientist to clone HIV and determine the function of its genes, which was a major step in proving that HIV is the cause of AIDS.

Like most movements, I have learned that the definition of feminism has expanded to include simply treating women like human beings.

(A thread for whoever feels like reading)


I have observed feminists on Twitter advocating for rape victims to be heard, rapists to be held accountable, for people to address the misogyny that is deeply rooted in our culture, and for women to be treated with respect.

To me, very easy things to get behind.

And the amount of pushback they receive for those very basic requests is appalling. I see men trip over themselves to defend rape and rapists and misogyny every chance they get. Some accounts are completely dedicated to harassing women on this site. It’s unhealthy.

Furthermore, I have observed how dedicated these misogynists are by how they treat other men that do not immediately side with them. There is an entire lexicon they have created for men who do not openly treat women with disrespect.

Ex: simp, cuck, white knight, beta

All examples of terms they use to demean a man who respects women.

To paraphrase what a wise man on this app said:

Some men hate women so much, they hate men who don’t hate women
I've seen many news articles cite that "the UK variant could be the dominant strain by March". This is emphasized by @CDCDirector.

While this will likely to be the case, this should not be an automatic cause for concern. Cases could still remain contained.

Here's how: 🧵

One of @CDCgov's own models has tracked the true decline in cases quite accurately thus far.

Their projection shows that the B.1.1.7 variant will become the dominant variant in March. But interestingly... there's no fourth wave. Cases simply level out:

Just because a variant becomes the dominant strain does not automatically mean we will see a repeat of Fall 2020.

Let's look at UK and South Africa, where cases have been falling for the past month, in unison with the US (albeit with tougher restrictions):


Furthermore, the claim that the "variant is doubling every 10 days" is false. It's the *proportion of the variant* that is doubling every 10 days.

If overall prevalence drops during the studied time period, the true doubling time of the variant is actually much longer 10 days.

Simple example:

Day 0: 10 variant / 100 cases -> 10% variant
Day 10: 15 variant / 75 cases -> 20% variant
Day 20: 20 variant / 50 cases -> 40% variant

1) Proportion of variant doubles every 10 days
2) Doubling time of variant is actually 20 days
3) Total cases still drop by 50%
