#OnThisDay 80 years ago, the United Nations Charter came into effect. The ideals that led to the UN's foundation – a human yearning for peace and unity – remain as critical as ever. And as humanists on #UnitedNationsDay, it is these ideals we uphold.

“I have a foreboding of an America in my children's or grandchildren's time — when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness.

The dumbing down of America is most evident in the slow decay of substantive content in the enormously influential media — the 30-second sound bite (now down to 10 seconds kind of celebration of ignorance.”

Mental illness is not a trend.

A reminder that just because more people are speaking up doesn’t mean it’s fashionable.

If you want to fill the gap between 1 and 2, 0.30 being a 'big gap', then just divide by ten [take the 1 away]!

more entries in my two-figure log tables!

14 1.15
15 1.18

18 1.26 [log 9 was rounded down]
19 1.28 [361 is about 360]
Please, just don't ask why.

*correction* the two-figure logarithm in base 10 of 9 is 0.95 - I can expect no one was interested in that

John Lenaghan @jtlenaghan.bsky.social · Aug 14

I can only suppose they might be useful when trying to plot logarithmic scales on standard graph paper.

John Lenaghan @jtlenaghan.bsky.social · Aug 14

Perhaps I could add the logarithms in my head to get the product? But these numbers are single digits! Lunacy!!

John Lenaghan @jtlenaghan.bsky.social · Aug 14

I don't know why my mind has been gripped with the invention of short base 10 logarithms for the single digit integers:
2 0.30
3 0.48
4 0.60
5 0.70
6 0.78
7 0.85 [49 is about 50]
8 0.90
9 0.96 [81 is about 80]

We are saddened by the recent passing of Jim Lovell, a four-time spaceflight veteran, commander of Apollo 13, and a pioneer of space exploration whose legacy continues to inspire so many to this day.

A NASA photo of Jim Lovell, astronaut, stood beside a globe.

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice

Physicists should revel in the diversity of ways to understand quantum mechanics

Nature survey shows that disagreement about the meaning of quantum physics remains strong, even 100 years in. And that’s OK.

This is what happens when 14 zettajoules of excess heat go into oceans every year. Here’s what that number looks like:

14,000,000,000,000,000,000,000.

That’s what fossil fuel does to oceans.

Actual engine failure during AI171 occurred in‑flight, triggered by fuel cutoff switch movement, not pre-flight startup malfunction.

Let me know if you’d like more details on the earlier December 2024 incident, maintenance logs, or the engineering concerns raised in the preliminary report.'

More chat with ChatGPT '✅ Summary

There is no evidence of ground engine start issues on previous flights of this aircraft.

The only known prior disruption was a technical cancellation in December 2024, unrelated to fuel control or engine startup.

John Lenaghan @jtlenaghan.bsky.social · Jul 12

This is a non-certifiable flight scenario, as the aircraft is not designed to be flown with ground engine mode active.

In reality, the aircraft would likely block takeoff (via FADEC interlocks, control law inhibitions, or ECAM/EICAS warnings) if it detected such a configuration.'

John Lenaghan @jtlenaghan.bsky.social · Jul 12

A chat with ChatGPT:-

'🚨 Implication (Hypothetical but Serious):

If someone managed to start the engines via the ground panel and took off without setting cockpit controls properly, the engines could shut down shortly after takeoff.
