When did probiotics become trendy? When did they become legitimate science and medicine? How do we differentiate between the pseudoscience of “raw food” movements and the clinical science of potential treatments for diseases from Alzheimer’s to ALS?
New Carbon Nanotube Technology
The research paper is “Versatile acid solvents for pristine carbon nanotube assembly,” and it describes a new acid solvent system that does not feature the extremely challenging types of acids traditionally used in carbon nanotube production.
What is Life?
This might sound like a philosophical question, but I intend it more like a scientific question. We’ve discussed this somewhat before, like in our post about the universe’s habitable zone, but I want to focus in a little closer on what life really is, on what makes one thing alive and one thing not alive, how we might go about defining the difference, and whether what we call life deserves the distinction we have hitherto applied.
Not-so-standard Model
While this is being hailed as the first potentially significant failure of the Standard Model, the Standard Model has really been struggling for years with a variety of problems
Solar Flares and Aquatic Suction Cups
I couldn't decide between two articles this week, so I decided to just post two. First up, a research paper I came across in Science Advances that studies how suction cups adhere underwater.
Space Debris Economics
Why should a private company make a business out of space debris removal? Alternatively, can space debris removal be made into a viable business model? This is one of those complicated questions that I recently saw reduced to a gross oversimplification in a news article. There were a lot of issues with the article, and I don’t want to dwell on it, but I think the biggest problem was its underlying, unstated assumption that the only viable business case for space debris removal as a commercial service was if the government was the customer, or regulated private space industry into becoming customers. The underlying argument of the article, therefore, is that there is no viable business model based on space debris removal.
Communicating Uncertainty
In a few months, when my review for Bernoulli's Fallacy goes live, we'll have a lot more to talk about when it comes to uncertainty, probability, and statistics. In the meantime, I wanted to share an article with you from the journal Science Advances, entitled "Earning the Public's Trust."
Conservation and Cycles
In any closed system, quantities must be conserved. Thermodynamics inform us that energy is conserved. Linear and angular momentum are both conserved, whether we’re looking at billiard balls in a Newtonian paradigm, or photons in a quantum system. Special relativity expands conservation even further to the equivalence between matter and energy. In a closed system, where nothing can escape, quantities are inevitably conserved.
A Few Thoughts on the US 5G Standoff
In case you haven't been following the barrage of news articles that don't actually have very much to say, here is the situation underlying this post.
The James Webb Space Telescope – A Christmas Present
This has been decades in the making, and I have been watching the observatory be delayed again, and again, and again for years now, so it was remarkable when it finally launched.
