I don't think people have quite internalized *how* the US became the global leader in science and technology. It's partially a story of massive global talent migration.

And it's important to get this story right if we want to maintain

 Around 1900, the US was a bit of a scientific backwater when compared to Europe. Most of the exciting work was being done in Germany and Austria, especially.

Then came three enormous waves of academic and scientific talent to the US.
1) First came a group of Jewish scientists fleeing persecution.

In a massive own-goal, 1930s Nazi Germany dismissed ~15% of the physicists who made up a stunning 64% (!) of their physics citations.
The group who fleed to the US included intellectual superstars like Albert Einstein, Leo Szilard, John von Neumann, and Edward Teller who formed the backbone of the Manhattan Project.
In a pithy quote, Churchill’s military secretary Sir Ian Jacob is said to have remarked that the Allies won “because our German scientists were better than their German scientists.”
And this wasn't just a 1:1 transfer of talent, this new intellectual community pushed our domestic fields to become more productive and drew in new inventors.
2) After WWII there was a scramble between the US and the USSR for the remaining German scientists.

With the Cold War looming, the US brought over ~1,600 scientists through Operation Paperclip and the Soviets ~2,500 through Operation Osoaviakhim.
While the Americans brought fewer experts, they may have reached the brightest individuals. Included in the group was Wernher von Braun, who became the chief architect of the Saturn V rocket, and Adolf Busemann, who pioneered the concept of swept wings in aeronautics.
So the Manhattan and the Apollo projects, arguably the two greatest US techno-engineering feats of the 20th century, were the result of international scientific talent embedded in American scientific institutions.
3) A third wave of international talent recruitment could be identified in the waning years of the Cold War, as Soviet mathematicians and other academics began to look for an escape hatch.
American universities suddenly had their pick of top Soviet scientists and were bidding against each other for the brightest stars. https://t.co/O2vKx2zpTF
There was even a policy proposal at the time to subsidize employers of these scientists, in the hope that we could assimilate all this newly available global talent as rapidly as possible.
https://t.co/i0QMZeQaEa
The net effect of these three waves has been America’s consistent domination of international science and technology.

Using the Nobel Prize in Physics as a rough proxy, American scientists were involved in only three of the thirty prizes awarded between 1901 to 1933.
From 1934 to 2020, Americans have been involved in roughly two thirds!

And a huge share of these Nobel laureates have been either first- or second-generation immigrants from these three waves.
For a period after the fall of the Soviet Union, the US was effectively able to rest on its laurels.

We were unquestionably the best location for scientific research and so most inventors/promising academics wanted to come here.
The results were stunning! Look at this chart of immigrant inventors from 2000 - 2010 from @william_r_kerr.
But that's been starting to change. A combination of three things:
1) US immigration restrictions are growing more burdensome
2) There are better opportunities to contribute to cutting-edge research at home
3) Other countries are starting to grow more *proactive* in their attempts to poach international talent
https://t.co/EYSUhofYeO
There's a lot more we could be doing! Obviously, our immigration system is a big barrier...
But we should go beyond these reactive measures and take a more proactive approach to talent immigration.

Today we grudgingly let the most talented individuals apply to live here; we do not actively recruit them.
Today it is concerns about identifying and stopping threats that dominates the day-to-day work of DHS.

The main job of immigration agents seems to be “avoid letting in terrorists” rather than “maximize the growth potential of the United States.”
To correct for this, I suggest we need a new department/office that has the sole mandate of finding and recruiting the most talented inventors and scientists from around the world and inviting them to live in the US.
The strength of the US has always come from being the melting pot for the world's greatest scientists and technical practitioners.

We are the R&D lab for the world and we should act like it.
Lots more on these topics and related ones in the full piece, I hope you'll check it out:

Two years ago on a weekend, I built a tool to make it easier to evaluate Twitter accounts. Since then 36590 people used it to analyze 55390 different Twitter accounts.

Over the last months @mmkaradeniz and I made a new version. We launched it last night:

@accountanalysis doesn't use machine learning or AI „magic“. Instead of telling users if an account is authentic or not, it helps them to evaluate the accounts themselves.

It visualizes the different features (date, time, type, app, etc.) of Tweets to make them interpretable. /1

@accountanalysis The core concept is still the same, but it looks much better and is easier to operate. Not only for the users, but us developers as well. Enabling us to continuously roll out new features in the future.

Side-by-side screenshots of the old and new version. /2


@accountanalysis Some people had questions what different charts displayed and how they could be interpreted. There are now explanations for all charts, that can be toggled on and off at any time. /3


@accountanalysis The selected/retrieved Tweet count moved to the top to make it clear that not all Tweets of an account are analyzed. 3200 is the API limit by Twitter. It's possible to get more through the Premium API, but I don't think people would pay $100+ for the analysis of one account. /4

There are only 3 real challenges to free speech at the tech level a) the need for CDNs at scale b) distortions of net neutrality c) nation-state firewalls.

All other claims are about social governance on private sites, where applying free speech doctrine is a stretch at best

Baseline free speech has expanded modestly since 1776 or whatever your reference point is.

About 20% beyond core case of government-critical speech in formally public spaces and media I'd say.

You can (for example) have more kinds of conversations in a bar without getting punched or kicked out by other patrons or management. You can teach more things in colleges than 100 years ago.

That's a genuine de facto increase in practical, informal free speech/expression.

But online free "speech" is, as @reneed has pointed out, not an expansion of free speech at all, but an expansion of reach. It is like the secondary freedom of the press to print as many copies as they can afford, not primary freedom to say what they want

If a newspaper wants to print more copies it has buy more printing equipment and front more upfront costs. Reach for a paper publication is not "free", but a function of desired circulation, which in turn is a function of demand prediction etc. But that logic is obscured online.

A long time ago I coded up a feature for SocialCoder which converts a link - any link - to a short URL. I use it all the time for sharing links to volunteer profiles and to volunteer opportunity listings.

The feature doesn't care what the link contains, it just hashes the URL, including any query params, and returns a shortened code.

More recently, around Christmas time, I added another feature where I can click a button to send a template notification to a charity that their new listing has been reviewed and published. I call it a next-steps email.

For the past few weeks, its all been working well. Its nice to keep automating things that previously were done by hand.

Fast forward to today.

A new opportunity listing is posted by a charity.

I review and publish it, tweet about it, then click a button to send the charity an emailed notification of next steps.

My key learnings: ⬇️⬇️⬇️


First, the BEAR case:

1. Bitcoin has surpassed all the bubbles of the last 45 years in extent that includes Gold, Nikkei, dotcom bubble.

2. Cyclically adjusted PE ratio for S&P 500 almost at 1929 (The Great Depression) peaks, at highest levels except the dotcom crisis in 2000.

3. World market cap to GDP ratio presently at 124% vs last 5 years average of 92% & last 10 years average of 85%.
US market cap to GDP nearing 200%.

4. Bitcoin (as an asset class) has moved to the 3rd place in terms of price gains in preceding 3 years before peak (900%); 1st was Tulip bubble in 17th century (rising 2200%).

MAHARAJA CHHATRASAL BUNDELA was the great Bundela King who revolted against the Mughal ruler Aurangzeb.
Chhatrasal Bundela was born in year 1649 CE in Maur Hill of Bundela region to Champat Rai and Lal Kunwar. He was the descendent of Rudra Pratap of Orchha.


His ancesters were the vassals of Mughal Emperor. He drew inspiration from his father and revolted against the alien rule of Mughals. He was just 12 yrs old when his parents died in fight against the Mughal Army of Aurangzeb in 1661.

When his beloved father attained martyrdom in the year 166, the young Chatrasal was present in the last battle of his father against the Mughal and from these valiant campaigns,..

..he gathered the courage to free Bundelkhand from Aurangzeb’s rule.
He joined the Mughals initially, and was recommended by the Rajput King Mirza Jai Singh to be recruited in the Mughal Army in order to support their Deccan Campaigns.


But serving the alien rule of Mughals which brought chaos and misery to Bundelkhand was unacceptable for Chatrasal Bundela and his father’s incessant struggle against the Mughals kept the fire of independent Bundelkhand alive in his heart.

SRI BANASHANKARI AMMAN, BANGALORE
#bharatmandir

Located in Southern Bangalore, this is one of the most popular places of worship in Bangalore City.
Devoted to Devi Banashankari, this shrine is visited specially during Rahukala which is believed to be an unfavorable time.


Somanna Shetty, a great devotee of Devi, brought this murti from Badami’s Banshankari Amma Kshetram.
It is said that many years ago, three ladies visited this shrine and requested the pujari to conduct puja for them. Since it was the inauspicious rahu kaal, the pujari refused.


However, upon their insistence, he conducted the puja. When he returned with prasadam, the ladies vanished. This made the people believe that they were none other than the Devi herself. Since then, the people perform poojas here during the Rahukaal.
@GunduHuDuGa


People use lemons as a diya. Lemons are cut from the centre and their pulps are removed, for pouring oil in them.
It is strongly believed that Devi removes all the troubles from the life of her devotees during the Rahukala although it is considered inauspicious for any pooja.

A thread on the life and achievements of Muhiyudin Sayyid Abdul Qadir Jillani RadiAllah who served Islam infinitely as the Reviver (Mujadid) of the 11th Century!


Muhiyudin Sayyid Abdul Qadir Jilani (RA) was one of the greatest Islamic Saint, Scholar, and Jurist. The honorific Muhiyudin denotes his status with many Sufis as a "reviver of religion". Jilani refers to his place of birth. He also carried the epithet Baghdadi.

[1]

Sheikh Abdul Qadir Jilani was born on the eve of the 2nd of Ramadan 470 AH. His birth was a great blessing for the Ummah. It was the arrival of the Sultan al-Awliya (King of the Awliya) of that era, which had been foretold for centuries before his birth.

[2]

When Hazrat Abdul Qadir Jillani was asked by someone what brought him to his high spiritual level, he said, The truthfulness which I promised to my mother. He related the following story:
"One day, on the eve of Eid al-Adhā, I went to my mother, who was then a widow and..

[3]

..and requested her, 'Send me to the path of Truth, give me permission to go to Baghdad to acquire knowledge, to be with the wise and those who are close to Allah. She cried, but she brought out 80 pieces of gold, which was all that my father had left as inheritance.

A thread on how absurd the UK is on transgender issues and how the UK got so transphobic

In 2015 Parliament held an inquiry looking into the state of Transgender equality. Trans people of all stripes outlined many different problems across many, many different areas.

As a result Parliament created a list of recommendations including legal recognition for non binary people, gender recognition act reform, allowing 16 year olds to change their legal gender and reform of NHS gender identity services.

The government under Theresa May ignored everything that was recommended except for Gender recognition act reform. This act came into law in 2003 and gave trans men and women (but not non-binary people) the ability to legally change their gender on their birth certificates.

The process at that time to change your birth certificate under the GRA was to make an application to a panel of cisgender people who would decide if you were sufficiently trans based on your payslips, photo ID and bank statements. You would not get the option to speak to them.

(Also this process cost £140 which is just a tax on being trans)
