Logic & First Principles, 18: What is time? (Thence, what of heat death? The proposed infinite past? Etc.?)
“What is time?” is a misleadingly simple question, one that soon surfaces many difficulties. That is, it is a philosophical issue: phil, being the study of hard big questions. However, it is clear that we need to ponder it here at UD at least at a basic level, if we are to examine relevant concerns […]
Churchill on rebuilding the traditional: “We shape our buildings and afterwards our buildings shape us”
According to news reports, already over US$ 1 billion has been pledged towards rebuilding Notre Dame: BTW: after the fire, a video tour: In today’s ever so polarised age [currently awaiting the infamous redacted Mueller Report on a two-year investigation into US President Trump], it is unsurprising that we see for example in Rolling Stone: […]
Notre Dame burns – updated
David Berlinski, who lives down the street from Notre Dame, writes, “The pompiers were in their glory last night, and, when I was allowed to return home as dawn was breaking, they were still there, red-eyed, exhausted, grim. The police, too. The great cloud of smoke had drifted to the west and south. Later that […]
Logic & First Principles, 17: Pondering the Hyperreals *R with Prof Carol Wood (including Infinitesimals)
Dr Carol Wood of Wesleyan University (a student of Abraham Robinson who pioneered non-standard analysis 50+ years ago) has discussed the hyperreals in two Numberphile videos: First: Extended: Wenmackers may also be helpful: In effect, using Model Theory (thus a fair amount of protective hedging!) or other approaches, one may propose an “extension” of the […]
Logic & First Principles, 16: The problem of playing God (when we don’t — cannot — know how)
In discussing the attempted brain hacking of monkeys, I made a comment about refraining from playing God. This sparked a sharp reaction, then led to an onward exchange. This puts on the table the captioned issue . . . which it seems to me is properly part of our ongoing logic and first principles reflections. […]
What are the implications of Julian Assange’s arrest in London?
Yesterday, a prematurely aged-looking Assange (he is 47) — a founder of Wikileaks and Australian — was arrested by UK Police after the Ecuadorean Embassy he has sought asylum in since 2012 withdrew its protection. The arrest raises questions on dissidents, privacy, protection of legitimate secrets, the public’s right to know more than officials, power […]
Have Scientists in China “brain hacked” monkeys?
. . . By inserting human genes? The UK Daily Mail summarises news reports making the rounds: The report details: A new study into the unique evolution of human intelligence has raised ethical concerns after Chinese scientists implanted human brain genes into monkeys to boost their development. Researchers inserted human versions of MCPH1, a gene that […]
SCI-TECH NEWSWATCH: Israel’s Beresheet spacecraft has a loss of comms and fails in a Moon landing attempt
The newly re-elected Prime Minister promises that Israel will persist. See Jerusalem Post for details (vids are in Hebrew): Israel’s Beresheet spacecraft fails to land safely on the moon Prime Minister Benjamin Netanyahu, who was at hand to watch the landing, said that Israel will continue to try landing on the moon. By JERUSALEM POST […]
BREAKING NEWS EVENT: First images of a Black Hole Event Horizon announced
A long-awaited development, thanks to an array of radio telescopes: BBC reports: Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy. It measures 40 billion km across – three million times the size of the Earth – and has been described by scientists as “a monster”. […]
Burning a brick in Fluorine — physical/chemical properties in action
In the demonstration below, a bit of acetone has been put on the corner of the brick to get the process started: This demonstrates the remarkable effects of inherent, embedded, intelligible structural, quantitative properties of fluorine and other elements and molecules. With lesser materials, we can see similar, even more spectacular effects: Notice, the table […]
Logic and First Principles, 15: On the architecture of being. Or, are certain abstract entities (“abstracta”) such as numbers, natures, truth etc real? If so, how — and where?
For some weeks now, an underlying persistent debate on the reality of numbers has emerged in several discussion threads at UD. In part, it has been cast in terms of nominalism vs platonic realism; the latter being the effective view of most working mathematicians. Obviously, this is a first principles issue and is worth focussed […]
Logic & First Principles, 14: Are beauty, truth, knowledge, goodness and justice merely matters of subjective opinions? (Preliminary thoughts.)
We live in a Kant-haunted age, where the “ugly gulch” between our inner world of appearances and judgements and the world of things in themselves is often seen as unbridgeable. Of course, there are many other streams of thought that lead to widespread relativism and subjectivism, but the ugly gulch concept is in some ways […]
LoneCycler on paradigms advancing one funeral at a time, etc
LC also has some food for thought for Friday fun: LC, 18: >>From the OP “Today’s dominant school of thought can become tomorrow’s dead theory, often one funeral at a time.” This is true. Every time they find another fossil they have to re-organize their phylogenetic trees. Some trees have been changed so many times […]
Harry’s food for thought on “Materialistic Scientism Is Fundamentally Irrational”
This is the first of two food for thought pieces coming from comments in the scientism thread: Harry, 7: >>Materialistic Scientism Is Fundamentally Irrational In order to demonstrate how a given instance of functional complexity might come about mindlessly and accidentally, one must first know how to create it intentionally. Then, one can at least […]
