Excerpt:

1- We Aren’t Totally Human – Almost half of the cells in our body don’t come from us. We have a universe of microorganisms, each of which brings their own DNA into the mix. From a BBC report:

“The human genome – the full set of genetic instructions for a human being – is made up of 20,000 instructions called genes.

But add all the genes in our microbiome together and the figure comes out between two and 20 million microbial genes.

Prof Sarkis Mazmanian, a microbiologist from Caltech, argues: “We don’t have just one genome, the genes of our microbiome present essentially a second genome which augment the activity of our own.

“What makes us human is, in my opinion, the combination of our own DNA, plus the DNA of our gut microbes.”

2- We share DNA with Bananas and Copied Viral DNA: Our closest genetic relative is the chimp, but we are connected to dogs and cats and even fruit flies and yes, bananas.

2022 Predictions

Excerpt:

Regional conflicts are heating up around the world. Resource needs will accelerate the trend. Fresh water in the Himalayas provide multiple countries who have nuclear arsenals. Oil and rare earth metals could also trigger a war. Climatic events are happening more often, so the cost takes money away from solutions while making the goals seem more obvious.

….

Resource depletion has no recommended debit treatment from accountants, but attribution analysis is going to do the work after the fact and charge companies for their past practices through the court system. I assume this is how the asbestos risk played out but I will need to learn more about similar historical events as these events play out. How should this enter your thought process as an investor? In 2021 I wrote 4 papers about climate; Climate System, Integrated Assessment Models, Impact of Climate Change on Investors and Municipalities and Climate Change. They are part of the SOA’s Environmental Risk Series. The impact of climate on investors will continue to evolve for many years. One topic of interest to me is how TCFD (disclosures) will play out – we could see “bad” investments like oil companies, gun makers and cigarette companies become privately owned. This would make it harder to apply peer pressure so is an important reminder to be careful what you wish for!

Excerpt:

Japanese contains a separate set of numerals used in legal and financial documents to curb fraud by preventing someone from adding strokes to previously written numbers (e.g. turning a 1 into a 2, or changing 3 to a 5).

Excerpt:

In the pre-computer days, people used these approximations due to having to do all calculations by hand or with the help of tables. Of course, many approximations are done by computers themselves — the way computers calculate functions such as sine() and exp() involves approaches like Taylor series expansions.

The specific approximation techniques I try (1 “exact” and 6 different approximation… including the final ones where I put approximations within approximations just because I can) are not important. But the concept that you should know how to try out and test approximation approaches in case you need them is important for those doing numerical computing.
