The Strait of Hormuz is turning into the key test of strength between the US and Iran. I've been thinking about what happens if it stays closed for an extended period. My conclusions might surprise you.

Oops, bit of unfortunate timing. Might be a while before oil shipments get going again.
Museohöyryjäänsärkijä Tarmo Kotkan merikeskus Vellamossa.

Höyryjäänsärkijän etukannelta kohti komentosiltaa.
Museohöyryjäänsärkijä Tarmo Kotkan merikeskus Vellamossa.
Laivassa pääsee kiertämään käytännössä kaikkialla, myös takimmaisessa kone- ja kattilahuoneessa.
🧵 kuvista pitkin laivaa. Kannattaa käydä, jos on Kotkaan asiaa.

Kyseessä on aksiaalilaakeri (thrust bearing kansainvälisellä), jolla potkuriakselista tuleva eteenpäin työntävä voima (tai taaksepäin, jos peruutetaan) siirretään laivan runkoon.
This can't be real. Or can it?
Euroopan Sveitsi 😍!
Olemme monesti todenneet, että jämäkkää yhteistä ilmastopolitiikkaa toteuttava EU on Suomen kansallinen etu.
Edistyksellinen suomalainen teollisuus on suuri kärsijä, jos EU nyt alkaa lipsua hyväksi todetusta päästökauppajärjestelmästä.

Ottaen huomioon että tien kuluminen on todettu olevan suhteessa akselipainon neljänteen potenssiin, tässä olisi oiva mahdollisuus pohtia mikä olisi kuljetusalan osuus näistä ylläpitokustannuksista.
Öljyn hinta pomppi jo yli 110 dollariin barrelilta. Pari huomiota:
1) Kallis öljy hyödyntää Putinia monta kertaa enemmän kuin mitä Iranin heikkeneminen sitä haittaa.
2) Talouden fossiiliriippuvuus on riski varsinkin Euroopalle. Nyt välitön stoppi kaikelle energiamurroksessa hidastelulle.
Yesterday, I gave colleagues from another university a brief tour of campus which included showing them the piece of chalkboard where Ernest O. Lawrence's Nobel Prize was announced to the group and confirmed. It just so happened that this was also in the 5min period before an undergrad lab started.
Optical illusion of a woman bent over some papers. Her sunglasses are pushed up and she is wearing a hair band so the top of her head looks exactly like a Muppet face
Sorry I know the world is in a terrible fix but I've been laughing at this for ten minutes now
Maintenance must have been interesting on these..
Jari, check the fuel injectors!
Jari: *groan*
This just in: Hevoset itse asiassa tykkäsivät liimatehtaasta!
Lions led by donkeys?
The European Council on Foreign Relations nails it. Climate regulation and investment etc ensures competitiveness and soft power as the world electrifies.
New video - hot take on Russian LNG tanker Arctic Metagaz burning, presumed sunk/destroyed, in Mediterranean today

Gas prices jumped again this morning and are on track to double - a stark reminder of our exposure to fossil fuel volatility.
The real solution isn’t more drilling, but moving away from combustion: electrify, use renewable power, and boost energy efficiency.
What does the potentially emerging energy crisis mean for Europe?
Yesterday I was in a media briefing with 75 journalists. Here is a snippet of what I told them.
”In the European Union, transport remains the only major economic sector where carbon dioxide (CO2) emissions have risen since 1990.”
#EU27 should not ease the regulations.

Just last week the German government gutted the heating law which was supposed to drive a transition away from gas.
The timing could not have been worse: Gas prices are up 50% today and this crisis could worsen significantly. This will happen again and again and the consumer pays the price.
The screenshot of the release notes reads: A new version of TeX Live Utility is available! TeX Live Utility 1.55 is now available-you have 1.54. Would you like to download it now? Release Notes: Changes Since 1.54 • Fix bug 137, homepage link in Help Book. • First release in a long time, since I don't use TeX anymore and resent the very idea of paying Apple annually for the privilege of giving away free and open-source software. Also, I'm really lazy. Please accept my apologies for all the annoying issues you've encountered in this mission-critical software. • Updated mirror list, which was three years out of date. • Added missing legacy mirrors, which was even more out of date. • Added an alert on startup when user tries Homebrew's lobotomized MacTex, because those lunatics left timgr but removed its database. Thanks for nothing, guys. Bug 142 and 144. • Use a custom user-agent to work around the Anubis bot trap on texlive.info. Can't wait to see what else breaks because of this, thanks to the profusion of degenerate Artificial Insemination fetishists scraping websites to feed their models. • Lists of countries in Repository/Continent are now sorted. No idea how you people let me get away with that one for the last fifteen years.
There's a "is anyone even reading this" sort of honesty you get in the software update release notes from a project that's been around for a long time.
Ihmiskunnan dilemma löytyy siitä, että meillä on ikävä taipumus nostaa johtajiksemme luonnehäiröisiä ja häikäilemättömiä opportunisteja. Tyyppejä, jotka janoavat valtaa ja ovat valmiita uhraamaan vaikka äitinsä sen edestä - puhumattakaan muista. Kyvykkyys ei kulje pyrkyryyden kanssa käsi kädessä.
Metsäteollisuus ry kääntää piippunsa yhä avoimemmin tiedettä ja tutkijoita vastaan.
Taitaapi olla tämä teollisuudenala ja erityisesti sen edunvalvonta, joka uutta starttia kaipaa.

By the way, tomorrow #Finland will have been independent for longer than we were a part of the Russian Empire.
Finland had been part of Russia for a total of 39,526 days.
It will be 39,526 days since independence on Monday, February 23, 2026.

5 German tourists have been rescued from “an ice floe carrying a sauna tent, a motorised saw and an onboard motor after they lost control of their DIY vessel in the Stockholm archipelago.”
They attempted to “create their motor-powered floating sauna when the swell from a ferry broke the ice.”

Another water cooled radial diesel engine: The Nordberg engine (for stationary applications) oldmachinepress.com/2014/01/12/n...
Historically, yes, most radial engines used air cooling as they were meant for aircraft, where you have a supply of fast moving cooling air. But that has limits, see e.g. the problems P&W had with back row cooling of their 4-row radial.
E.g. the Zvezda mentioned upthread was water cooled.
And a radial arrangement keeps the crankcase decently short and stiff (don't want the crankshaft flopping around like a wet noodle) without a high weight penalty.
Alas, gas turbines happened and took away the impetus to create such powerful piston engines.
