Maybe not the ideal location
This is an answer to the suggestion of throwing money to build up an ev industry and my thinking it can not work here

Can you compare the US business ecosystem to us?
Tax rate, red tape, green tape, work legislation, minimum wage,tax code complexity,etc
Look at the state of NASA now after years of socialisation/europeanisation of the US society.
They have to borrow Russian rockets to even send supplies to the ISS
People blame budget cut, their 2020 budget is 22 billions USD and they still benefit of trillions invested in military expenses
They became old tired administrative
Military R and D creates a fertile environment for advances: jobs for uni graduates, critical mass etc
But we are becoming the world biggest importer of weapons (ABC yesterday)
Do we think the Boston Dynamics robots are going to work in factories?

This is pretty scary actually....

Leaders yes and reflection of military expenses yes,we may not want and anyway can not afford
We have to start nimble but throwing money is rarely the way to go
I could write for ages how the system works here in Australia,
how i devised 3 apps/ softwares and
How the "system" limited crashed them
One is still used by a corporate giant but not spread: corporate giant fear of competition ,monopoly, impossibility of getting research funding or bank founding to start a standalone business
That is number one
Second was health related: you know the saving lives...no one touch it because of liability potential: better let people die than saving some in case it may not work a few percent of case: western system of suing and blaming
3rd one was offering a cheap option in competition with a not for profit tax funded organisation
$50 vs $2000.who do you think win?
So if i build an app to help refugees in women shelters to reduce their greenhouse gas emission and explore their sexual diversity, i can guarantee grants and money flowing, but for a life or technology affecting work, good luck if you are not in #trend
My last (and this will be the last) work is now China owned and world patent pending ..
But the startup there was running in an environment which can not be compared with us here in Australia, and this is why we do not have an Australian office/branch..nor of course factory
I commuted with china for 1.5 year..welcome CO2..
I have the feeling we need anasty shock if we are to ever change and produce proper science here, or we will just carry on our slow Argentina-tion

In that case he should state which studies are false and back it up with evidence.

This is like saying "50% of police are corrupt". It's easy to say but a lot harder to prove.

My experience, anecdotal of course is that is more like 85%. But I can't prove that objectively.

There is however, a well-known crisis of repetitionin the scientific process in many Fields.
 
A few articles i read are pointing to a fact which makes a lot of sense:
As we all know, magnetic poles are moving rapidly lately..has happened before and will happen again
But there are multiple side effects quite logical, a change of magnetic pole location will have significant effect on magma flows known to be mostly iron, and by changing flows,, we can expect an increase /changes of earthquake and volcanic activity, with thinking about it potentially some volcanos turning live again while others would die
I do not think this should draw much polemics but sure people will get angry anyway
Another personal twist is: if poles changes then radiation exposition do too, as different areas of earth will be subject to different level of protection from our magnetic field
If these high energy particles and light waves hit open sea instead of ice or land, can we not expect some effects: be it skin cancers, plancton growth,even overall thermal balance..aka global warming or cooling?
 
That was an interesting story Wayne quoted.
For the record it is worth checking out the original paper.

In medical research there is always a challenge to ensure research around drugs is valid. Big Pharma takes a very close interest in ensuring its interests are served .

I'm sure a number of posters would be aware of the double split physics experiment which opened the door to quantum physics.

But if you havn't seen/heard of it or want to refresh your memory and its implications this 5 min explainer is well worth a look see.

Nice one, as to be honest, I remember the experience name and I saw it/have vague recollections yet can not even remember the concept. good refresher @basilio
 
I've just finished reading this, which I think is one of the best and entertaining explanations of Einstein's Special Theory of Relativity as it relates to time travel. It clearly explains why time travel (into the future) is not just some mathematical abstraction but will someday be possible when we have the means to reach the speeds necessary to notice material differences in the elapse of time as witnessed by different observers. Even today, technology such as GPS requires that minute differences in elapsed time due to the speed of satellites in orbit needs to be taken into account, otherwise the positioning of tracking devices on earth would be out by many metres.

The book is described as being written for intellectually curious people and does not require any math beyond junior high school level (Pythagorus' theorem is about as advanced as it gets). In fact the book goes out of its way to avoid mathematical formulae, which are kept to footnotes for those who are interested in such stuff.

I haven't seen it in bookstores, but the person who gave it to me said it is available on Amazon (you may have to access the US site) in hardback and Kindle soft copy formats.

Thanks bellenuit $15 Amazon out of the UK
 
As a follow up to the double slit experiment consider this video - and in particular the conclusion.

I am sure I ordered this book but ended up with "The Order of Time" by Carlo Rovelli which completely destroyed my understanding of time.


BTW you are all just events.
 
Douglas Hofstadter, the author of Godel, Escher, Bach: An Eternal Golden Braid is 75 today. A great book that I have attempted to fully read many times but failed. The book explores common themes in the lives and works of logician Kurt Gödel, artist M. C. Escher, and composer Johann Sebastian Bach. The book expounds concepts fundamental to mathematics, symmetry, and intelligence. It won a Pulitzer prize for General Non-Fiction.

An interesting conundrum/paradox in the book, which I hadn't encountered before, but came across today is:

How many errors do you see in the sentence below?
"This sentense has three erors."

It seems obvious, then not so obvious as you think more about it.
