A Possible Solution To The Energy Storage Problem?

"As we look to transition to our electric future, researchers are still stumped about how to store the electricity generated by inconsistent renewable power sources like solar and wind. Now, scientists report progress in storing energy by shifting the shapes of molecules, a solution that could be directly combined with photovoltaics. This idea makes a lot of sense — at least to me. Let’s take a look."

Science Itself Is In Crisis

There is much scientific activity but such has yet to lead to the type and amount of progress that has happened historically. Sabine Hossenfelder exposes the roots of this situation: a focus on the quantity of research rather than the quality. Click on the link below for the details:

Scientific Progress is Slowing Down. But Why?

Another Look At Geothermal Energy

"Geothermal energy is everywhere, just right under our feet. So could it be the solution to climate change? I used to think it was just too difficult and expensive to make much sense in most places, but some recent advances have made me rethink. Let’s have a look."

Click on the link below for another video from Sabine Hossenfelder regarding geothermal energy. She appears to be giving it a positive look now (see prior posts):

Should We Be Handwriting More?

"Do you still write by hand? Anything besides shopping lists? A new study looked at what happens in our brain when we write by hand or type on the keyboard, and it makes a really strong case for handwriting. I personally quite like handwriting and I am totally convinced it’s good for, well, something, so I should be extra sceptical of this finding. But let’s have a look."

The Big Bang Debunked?: A Clarification

"I was rather surprised when I recently learned that the British science communicator and ex-particle physicist Brian Cox supposedly debunked the Big Bang with a creation story, no less than in a BBC documentary. I had a look at the clip and I think I know what happened."

Reality Can Be Counter-Intuitive

"What is better, planting trees or covering the same area of land with solar panels? A group of geoscientists from Israel just looked at this, and they say that solar panels come out way ahead. Let's have a look at what the paper says."

Another Biogenesis Hypothesis

"Scientists have long speculated that life didn’t begin on Earth but in space. According to a new preprint, life could have come from intergalactic gas clouds, so-called molecular clouds."

Long COVID: What You Need To Know

"Estimates say that as many as 1 in 10 people who had COVID were still affected more than 3 months later. This health condition has become known as long COVID. In this video, we will discuss COVID, how long it lasts, how common it is, what you should do if you think you’re affected, and more."

The Purpose Of The Universe

Purpose: the reason for which something is done or created or for which something exists
- - - - - - -

"If people knew one thing about Steven Weinberg, it’d be a quote from one of his books: 'The more the universe seems comprehensible, the more it also seems pointless.' In this video, I want to speculate about what he might have meant. Is the universe pointless?"

A Look At Capitalism

"Is capitalism the reason the world is going to hell in a handbasket? Or is it going to save us? What is capitalism anyway? How does money work and when do free markets fail? This video briefly summarizes a dip I did into microeconomics literature in a dark hour of my life."

Click on the link below for a video from a physicist looking open-mindedly at capitalism. I take the view that REGULATED CAPITALISM is the way to go, which the USA presently is far from :

Population: Too Many Or Not Enough

"Should we worry about overpopulation or, as Elon Musk has argued, should we worry more about underpopulation? How many people could live on our planet and how close are we to reaching the 'Limits to Growth'? In this video, we look at how much we know and what we can conclude from this."

"I Did My Own Research"

This is what one can hear or read from the anti-science folks. However, if one is a science-based thinker, one does need the proper methods and tools to find out what is the scientific consensus on any topic. Click on the link below for a video by Sabine Hossenfelder outlining a step-by-step process for the non-scientist/researcher:

Do your own research, but do it right

For starters: 

  • Be knowledgeable about the elements of scientific research
  • Don't cherry-pick
  • Never trust 2nd-hand sources - - - but look at them anyway
  • If there is data, look at it and don't trust the text

Physics And Self-Reflection

"Some physicists are claiming that there is something 'wrong' with our understanding of the universe. Oftentimes, it's just to justify asking for funding for new experiments, a better detector, a new telescope, or a bigger collider, but what if there's something more than that? Do we have evidence of new physics? Or not? In this video, we will look at dark matter and dark energy, quantum gravity, the mass of the Higgs-boson, neutrino masses, and the matter-antimatter asymmetry."

A Look At Moore's Law

"In the past 10 years or so, tech specialists have repeatedly voiced concerns that the progress of computing power will soon hit the wall. Miniaturization has physical limits, and then what? Have we reached these limits? Is Moore’s law dead? That’s what we’ll talk about today."

Personality Tests: Are They Worthwhile?

"Have you ever taken a personality test? I certainly did. Recently I began wondering what the Myers Briggs and Big Five tests actually tell me. Is there science behind those tests? Or are they just better horoscopes? In this video, I'll tell you what I've learned."

I took all these personality tests. What does that tell me?

Greenwashing

"Many companies try to appear environmentally friendly without making a real difference, a strategy that’s been dubbed 'greenwashing'. So, is calling a product or service 'eco-friendly' just a ploy of companies to get more money out of us? What are the consequences for climate change? And how can we spot those fake claims? That’s what we’ll talk about today."

Transitioning To Electric Vehicles

In the last few years, the media promotion of electric vehicles has seen a noticeable increase. However, what are the facts and realistic expectations regarding such? Click on the link below for a concise evidence-based analysis of the issue by Sabine Hossenfelder:

AI, Consciousness, And Intelligence

"Artificial Intelligence continues to be the talk of the town, but how intelligent are they really? Come to think of it, what do we mean by "intelligence" anyway? In this video, we'll look at IQ tests for humans and for computers and see how current AIs have scored."

It's not AI consciousness that worries me, but their intelligence

Transhumanism And Other Manipulations Of Human Biology

"Technological enhancements and implants are becoming more popular amongst a group of transhumanists who call themselves 'grinders'. Are we coming closer to an age of cyborgs? Is genetic screening and editing ethical? Has biohacking lost all meaning? What are nootropics? That's what we'll talk about today."
