Let's talk about Avi Loeb and his theory about alien

 First, I should disclose that I work at the fame research facility as Dr. Loeb, though I work in a different department and to my recollection we've never met.

He's a scientist; I'm in computer support.
With that out of the way...
The interview above is worth a read, and a lot of serious thought, because there's an idea there that's really critical to science, and it isn't whether or not aliens have visited (exactly).
It's about how fashion and culture and taboo have an unfortunately strong effect on science.

In particular he compares his theory on alien visitation with the multiverse theory.

Which of these is more deserving of ridicule?
Science is fundamentally a structure for forming hypotheses and then (critically) testing these hypotheses to see if they should be kept, rejected, or modified.
And so a big part of his point is that we just discovered an object passing through our galaxy that is truly bizarre compared to any other known objects we've ever seen.

So bizarre that there's no really good theory for what it might be. Except maybe for Dr. Loeb's theory.
He's postulated that it could be a cast-off solar sail from an alien probe. On a simple matter of facts, it's a great fit. It explains the bizarre shifts in brightness, and it explains the bizarre acceleration as the object moved out of our galaxy.
But as I said and as he says in the article, science is all about testability. This is an object. It exists. We have seen it. We can look for more objects.

The hypotheses we form can and should help guide us in how we look.
So if we think it might have been an alien solar sail, versus a long skinny low mass comet with an invisible jet mechanism, these hypotheses point to different things we can look for.
So why not just say we should look for more? Why be like "Aliens!"? Because it affects how we look, not just whether we look.

And because "Aliens!" is based on observable phenomena: us.
It's a fascinating point that is easy to overlook. The "Aliens" theory has at it's core a phenomenon known to exist already: lifeforms that can launch probes through space. Because we know we exist.

The competing theories are all about phenomena with NO prior observations.
So just on that, "Aliens!" ought to be the leading theory here because it's the only theory that matches any known previously observed phenomenon. And yes, there's some spin in this viewpoint, but it's worth consideration.
He also talks about it relative to other popular theories like the multiverse theory.

Why is it unsafe to talk about "Aliens!" but safe to talk about the "multiverse"?
The multiverse theory is popular these days because it has invaded our culture in seemingly every sci-fi show in existence, and from there, it has turned into a sort of de facto background "fact" in our culture.

Yet the notion has always (to me) been utterly absurd.
As shown in popular culture, multiverse are just a way for writers to explore "what if?". Generally, what if some character had different life experiences.

But this isn't the scientific theory of the multiverse at all.
In the science viewpoint, every possible quantum state of every particle in existence, does exist in some alternate universe.

But under this theory, there'd be an infinite number of "adjacent" universes spinning off of that one single particle at the tip of my pinky toe.
And another infinity of universes for every other particle in the universe.

In such a multiverse system, the "nearest" (by measure of similarity) million, trillion... heck the nearest googol of alternate universes would be utterly identical to ours.
That is, the single particle state differences that differentiated those universes from this one are most likely not even in our observable universe.
In some of these shows (e.g. D.C. Comics, though they're not the only ones) they start to number the Earths to keep track, so there's like earth 32 and earth 18 or whatever.
But in reality Earth 9099813298719283701928374018972348712397108570385710234871092847019283703287019823470198327018732 would be identical to our Earth down to the last measurable particle.
To misquote "Contact", that seems like an awful waste of spacetime.

And really, an utterly pointless one.
So unlike the alien probe theory, we have absolutely no way to test the multiverse hypothesis. It's a mathematical castle in the sky (which probably all spins from a misunderstanding of Schroedinger's thought experiment).
So if the multiverse isn't really science at all, but just some sort of mathematical fancy, or better yet fiction, why is it that we act like the multiverse is science and that the possibility of aliens is not science?
In other words, Professor Loeb is mocked for bringing up the possibility of an organic life form developing technology, even though we KNOW that happens, yet countless scientists talk about the multiverse almost as a given, though we've never seen an alternate universe.
This disparity is not science. It is simply what is in fashion and what is not.
I should probably mention that I did a speculative thread about Oumuamua almost a year ago. It's worth mentioning in this context because I was in fact talking about a testable hypothesis related to Oumuamua.

https://t.co/XiHA9cRwjR
In particular, this tweet from that thread is about the testable hypothesis (though I didn't express it that way):

https://t.co/hj1ytCbFDH
In other words, I had this hypothesis that I got from Dr. Loeb, and created a test in my head without even thinking of it that way.

The test was, if a small object showed up in orbit around Earth in the next couple of years after Oumuamua we should be extra suspicious of it.
And one did.

(Hint: speaker is on the

In recent years ML models have worked from research labs to production, which makes ML security important. Adversarial ML research studies how to mess with ML

For example by messing with the training data (c.f. Tay which became super-racist super-fast) or by foiling ML models by changing inputs in ways humans can't see.


Prior work considers ML models in a standalone, mathematical way
* looks at the robustness in an isolated manner
* doesn't look at the whole ecosystem and how the model is used -- ML models are running in real hardware with real software which has real vulns!


This talk focuses on hardware-level vulnerabilities. This is particularly interesting because these can break cryptographic guarantees (because those are outside of their threat models)
e.g. fault injection attacks, side-channel attacks

1) Science denial is destroying our societies, our civilization. Various vested interests, usually right wing ideologues find various scientific facts and information contrary to their agenda, so through propaganda they are orchestrating the public into denying this science.

2) We are seeing this with regard to the COVID virus, where a range of denial is being promoted, ranging from absolute denial the virus exists, to different levels of denial, such as only some people are vulnerable to the virus, to facilitate business as usual.

3) For a long time, to promote business as usual, vested interests have been promoting the denial of the climate and ecological crisis through propaganda. The aim being to create a large enough body of public denial to prevent action which can change anything.

4) We have seen similar patterns over a long time, such as when tobacco companies promoted denial of the emerging scientific evidence of how harmful and addictive tobacco smoking was. This further denial uses exactly the same methods.

5) Understandably, the public can't be educated about everything and have to rely on experts to inform them of concerns about threats to public safety. Malicious vested interests take advantage of this by using pseudo-experts to misinform the public.

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

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


Sophia Jex-Blake fought for women's rights to study medicine. She was involved in founding two medical schools for women.

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


Alice Augusta Ball developed the "Ball Method", the most effective treatment for leprosy during the early 20th century. She was 23.

All modern research questions frame your mindset and self-frame research paradigm. Broad thinking: how little of everything can a citizen survive on; how cheap can your upkeep be? /1


When an American patient lands in an Austrian hospital for a back problem, a doctor tells him to perform a set of exercises.

- How many?
- Do you have anything else to do? /2

This interchange illustrates two mindsets colliding at bedside. How little can I get away with vs there is no limit to effort when it comes to your wellness. /3

When you were robbed of movement, somebody started selling you exercise. To understand that digging a ditch, to build a house, or to carry a child around, or waking to your grandparents for an hour is not the same as jogging on a treadmill... will reveal what research hides.
/4

When I talk about doing a purposeful activity outdoors, I look at complexity of movement, purpose, meaning, sun, and air, even an opportunity to meet a neighbor... that is now reduced to a calcium pill, vitamin D, an antidepressant, an osteoporosis shot, and an oxygen tank. /5

Hello Dear Tweeples!

It’s Siddhars time of the week! Last week I shared story of Guru (Machamuni or Yogi Matsyendranath), this week I bring you information on his Shishya.

#Thread on Gorakanathar Siddhar.

@LostTemple7


His origin story is interesting, though I couldn’t verify it’s authenticity, so not sharing the story here. He’s shishya of Machamuni Siddhar and also learnt from Agasthiya Siddhar.

@HelloNNewman @RajiIndustani @Kishoreciyer1

Unlike other Siddhars, he is depicted as either with a Tiger or seated & wearing Tiger skin. While I couldn’t find any explanation for this. My interpretation is as follows:

Tiger is a predator that lurks around and attacks unexpectedly.


Our 5 indriyas and 5 vikitis also similar to Tiger, they lurk around and attacks our thoughts when we’re least expecting. Gorakkar is said to have mastered these aspects, thus to denote this, he shown with Tiger.

@Itishree001 @VarierSangitha @jananisampath

Gorakanathar or Gorakshnath (as he’s known in the Nath Sampraday) is celebrated Guru in both Northern and Southern part of India. He’s one of the NavNath in Nath Sampraday and also 18 Siddhars of Tamil tradition. During his life, he’s travelled Indian subcontinent extensively +

Again sharing bank nifty intraday weekly straddle. How to play by selling straddle.
Mostly will work on Monday to Wednesday. Sometimes on Friday.
Why to pay your money to learn this if u can get it here.
U need only practice.
Let’s go.

Say bank nifty future is at 32000.
Sell both 32000 call and put.
Considering current volatile market lest say premium on Monday morning is 350 on both sides.
Sold with 700 points combine premium.
If bank nifty will trade in narrow range say +\- 100 hold it.
If moving 200 points

then exit previous sold straddle. Sell new one. Let’s say BN moved +200
Now sell 32200. If bank nifty will move here within range then u will get profit through theta decay. Follow same procedure for next 150-200 pts move.

This is only for single straddle sell position.

Now in second case sell three straddle. 31900/32000/32100
In case of 100 points move no need to change.
If 200 + then future is 32200.
Exit 31900 and sell 31200 straddle.
If moving another 100 then exit 32000 and sell 32300. Continue same with 100 points move.
If no move then

it will consolidate between 32000-32200 or 32100 to 32300 and u will get theta decay.

This is for normal move. Sudden big move may come anytime. So keep SL in system.
If u r selling at 350-350 then keep SL in system 475 for both legs.
Practice it. No need to attend webinar.

Post Independence, Army wanted to select the most experienced Indian commander as Army chief. But Nehru without consulting anyone appointed Gen Rob Lockhart, a senior British Army officer as the Commander-in-Chief (C-in-C) of the Indian Army.


Most people were shocked to know that Nehru selected a British Man after fighting for independence for over 200 years! Major Gen A A ‘Jick’ Rudra of the Indian Army was completely upset with the decision.


One day Lockhart met Nehru with a strategic plan and proposed many government directive defence policies for the country. He placed it on the table and explained the point to PM Nehru. After a while Lockhart walked out of the room and met AA Jick Rudra,+

Lockhart looked shell shocked and stunned. When asked what happened he said “The PM took one look at my paper and blew his top. Rubbish! Total rubbish! We don’t need a defence plan. Our policy is ahimsa (non-violence). We foresee no military threats. Scrap the army!”

One year after the incident the Kashmir crisis had increased and Gen Lockhart used to exchange ideas with the Gen Douglas Gracey who was commander in chief of Pakistan Army.There were many infiltrations along the border which Lockhart knew and took no action. But Lt Gen Cariappa+
