I expect ideas of mapping functions are only a couple of hundred years old at most, and really quite obscure to most people who are just familiar with the concept of 'maps' and 'mapping' things 'out'. In functi

I like how the array named 'map' reflects our original use of this word, rather than the special meaning which it has acquired to programmers. In Javascript and other languages 'map' has become a kind of "functional

I think there is also a strong instinct not to harm or kill our peers which only by exception can be over-ruled - by emotional trauma or threat. We can't detach destructive tendencies from dynamic cultural circumstances. Fireside socie

Breastmilk is the evolved complete nutrition for babies. Various milk formulas are developed towards that goal. You cant compare these with the assumption they do perform the same - it would be like using Soylent 2.0 as the control for adul

The UK's agreed carbon budget is to achieve 80% reduction by 2050, and the US administration is no longer even officially interested in its own. Those agreements are bust on their own terms never mind the idea of zero emissions. Don&#x

The goal is not a certain level of emissions, as you say - negative emissions would be desirable. A 50% reduction will be a great improvement, a 90% reduction will be almost as good as 100%. 110% even better... Our task is to reduce emissio

"they can spray as much pesticides as they want" equates substances with pesticidal properties like pepper with the likes of glyposate and chlorpyrifos products. It was a deceptively simplistic statement from the get go, which y

There is generally only one organic certification program per country, in the US it is administered by the United States Department of Agriculture [0] - which also administrates most standard regulations. Of course, no organically certified

So this then claim stems not from knowledge but from a "seemingly logical deduction". It is clear that there is no actual substance to this idea that "organic farms often use more pesticides" - even the notion is false t

Right, those are ubiquitous chemicals and compounds with a relatively low uncertainty to their ecological and biological impacts. Unlike for example - synthetically augmented glyphosate compounds, and other contentious products which organi

CO2 per kWh focuses purely on the issue of attained performance of electricity production - which is the main matter for production technology to concentrate on. Dividing by GDP flatters the view of wealthier nations, and GDP itself is not

Considering reduction of pesticide use and exposure is one of the main objectives of the organic movement, which has been developing for over 60 years now - it would be a hopeless situation if it resulted in "just as much, if not more,

I noticed US has around the same magnitude of cattle as it had wild ranging buffalo a few centuries ago. That doesnt seem like a great conversion. Those forest reserves are enviable, the UK is lucky if it has a couple of squares left.
