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.

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.

Legacy site *downloads* ~630 KB CSS per theme and writing direction.

6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices

https://t.co/qyl4Bt1i5x


PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.

735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

https://t.co/w7oNG5KUkJ


The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.

The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
1. One of the best changes in recent years is the GOP abandoning libertarianism. Here's GOP Rep. Greg Steube: “I do think there is an appetite amongst Republicans, if the Dems wanted to try to break up Big Tech, I think there is support for that."

2. And @RepKenBuck, who offered a thoughtful Third Way report on antitrust law in 2020, weighed in quite reasonably on Biden antitrust frameworks.

3. I believe this change is sincere because it's so pervasive and beginning to result in real policy changes. Example: The North Dakota GOP is taking on Apple's app store.


4. And yet there's a problem. The GOP establishment is still pro-big tech. Trump, despite some of his instincts, appointed pro-monopoly antitrust enforcers. Antitrust chief Makan Delrahim helped big tech, and the antitrust case happened bc he was recused.

5. At the other sleepy antitrust agency, the Federal Trade Commission, Trump appointed commissioners
@FTCPhillips and @CSWilsonFTC are both pro-monopoly. Both voted *against* the antitrust case on FB. That case was 3-2, with a GOP Chair and 2 Dems teaming up against 2 Rs.

दधीचि ऋषि को मनाही थी कि वह अश्विनी कुमारों को किसी भी अवस्था में ब्रह्मविद्या का उपदेश नहीं दें। ये आदेश देवराज इन्द्र का था।वह नहीं चाहते थे कि उनके सिंहासन को प्रत्यक्ष या परोक्ष रुप से कोई भी खतरा हो।मगर जब अश्विनी कुमारों ने सहृदय प्रार्थना की तो महर्षि सहर्ष मान गए।


और उन्होनें ब्रह्मविद्या का ज्ञान अश्विनि कुमारों को दे दिया। गुप्तचरों के माध्यम से जब खबर इन्द्रदेव तक पहुंची तो वे क्रोध में खड़ग ले कर गए और महर्षि दधीचि का सर धड़ से अलग कर दिया।मगर अश्विनी कुमार भी कहां चुप बैठने वाले थे।उन्होने तुरंत एक अश्व का सिर महर्षि के धड़ पे...


...प्रत्यारोपित कर उन्हें जीवित रख लिया।उस दिन के पश्चात महर्षि दधीचि अश्वशिरा भी कहलाए जाने लगे।अब आगे सुनिये की किस प्रकार महर्षि दधीचि का सर काटने वाले इन्द्र कैसे अपनी रक्षा हेतु उनके आगे गिड़गिड़ाए ।

एक बार देवराज इन्द्र अपनी सभा में बैठे थे, तो उन्हे खुद पर अभिमान हो आया।


वे सोचने लगे कि हम तीनों लोकों के स्वामी हैं। ब्राह्मण हमें यज्ञ में आहुति देते हैं और हमारी उपासना करते हैं। फिर हम सामान्य ब्राह्मण बृहस्पति से क्यों डरते हैं ?उनके आने पर क्यों खड़े हो जाते हैं?वे तो हमारी जीविका से पलते हैं। देवर्षि बृहस्पति देवताओं के गुरु थे।

अभिमान के कारण ऋषि बृहस्पति के पधारने पर न तो इन्द्र ही खड़े हुए और न ही अन्य देवों को खड़े होने दिया।देवगुरु बृहस्पति इन्द्र का ये कठोर दुर्व्यवहार देख कर चुप चाप वहां से लौट गए।कुछ देर पश्चात जब देवराज का मद उतरा तो उन्हे अपनी गलती का एहसास हुआ।
THIS.

Russia hasn't been a willing partner in this treaty for almost 3 decades. We should have ended the pretense long ago.

Naturally, Rand Paul is telling anyone who will listen to him that Trump is making a HUGE MISTAKE here.


Rand is just like his dad, Ron. 100% isolationist.

They've never grasped that 100% isolationist is not 'America First' when you examine it. It really means 'America Alone'.

The consistent grousing of pursuing military alliances with allies - like Trump is doing now with Saudi Arabia.

So of course Rand has also spent the last 2 days loudly calling for Trump to kill the arms deal with Saudi Arabia and end our alliance with them.

What Obama was engineering with his foreign policy was de facto isolationism: pull all the troops out of the ME, abandon the region to Iranian control as a client state of Russia.

Obama wasn't building an alliance with Iran; he was facilitating abandoning the ME to Iran.

Obama wouldn't even leave behind a token security force, so of course what happened was the rise of ISIS. He also pumped billions of dollars into the Iranian coffers, which the Mullah's used to fund destabilizing activity [wars/terrorism] & criminal enterprises all over the globe
Knowledge & Bharat : Part V

The Curriculum of Vedic Education :
According to the Ancient Indian theory of education, the training of the mind & the process of thinking, are essential for the acquisition of knowledge.

Vedic Education System delivered outstanding results.  These were an outcome of the context in which it functioned.  Understanding them is critical in the revival of such a system in modern times. 
The Shanthi Mantra spells out the context of the Vedic Education System.


It says:

ॐ सह नाववतु ।
सह नौ भुनक्तु ।
सह वीर्यं करवावहै ।
तेजस्वि नावधीतमस्तु मा विद्विषावहै ।
ॐ शान्तिः शान्तिः शान्तिः ॥

“Aum. May we both (the guru and disciples) together be protected. May we both be nourished and enriched. May we both bring our hands together and work

with great energy, strength and enthusiasm from the space of powerfulness. May our study and learning together illuminate both with a sharp, absolute light of higher intelligence. So be it.”

The students started the recitation of the Vedic hymns in early hours of morning.


The chanting of Mantras had been evolved into the form of a fine art. Special attention was paid to the correct pronunciation of words, Pada or even letters. The Vedic knowledge was imparted by the Guru or the teacher to the pupil through regulated and prescribed pronunciation,
