Atkinson's law - if an online debate about science goes on long enough the probability that one party compares the other party to a climate change denier, flat-earther or anti-vaxer increases.

One aspect of using cloud based simulation software rather than running the application locally on a PC that I have come to appreciate is that your work is constantly saved. Even if your computer crashes, the simulation will keep running out there in the cloud somewhere.

Trump's Hormuz Blockade: How It Backfires, and What Iran Can Do Next After marathon peace talks in Islamabad collapsed Sunday, President Trump announced on Truth Social that the U.S. Navy will "immediately" begin blockading any and all ships entering or leaving the Strait of Hormuz — framing it as a response to Iran's toll regime and its refusal to abandon nuclear ambitions. Trump described the move as "all or none" — meaning no ship passes until Iran relents, targeting the selective access Iran had been granting to friendly nations like China and India while restricting others or charging tolls of up to $2 million per vessel. The logic, on its face, sounds like leverage. Strip Iran of toll revenue, deny it economic benefit, and force capitulation. But the strategic reality is far more complicated — and the blowback, both short and long-term, may prove catastrophic for Washington. SHORT-TERM BACKFIRE: 1. The U.S. Just Did Iran's Job For It Iran's greatest weapon in this war has been the threat of Hormuz closure. It was already choking the strait and collecting tolls. What Trump's blockade does is complete the closure more decisively — and now the world will blame Washington, not Tehran, for the shutdown. Iran wanted a pretext to lock down the strait without appearing as the sole aggressor. Trump handed it to them. 2. Oil Markets Will Detonate As much as 20% of the world's petroleum transits the strait each year. Iran had already caused severe disruption. A full U.S. blockade — interdicting every vessel, including those previously moving under Iranian-granted clearances — means zero flow from the Persian Gulf. Saudi, Emirati, Kuwaiti, Qatari, and Iraqi oil all exit through Hormuz. The U.S. isn't just targeting Iran here. It's cutting off its own allies' export arteries. Brent crude, already elevated from weeks of conflict, will spike to levels that dwarf any prior energy shock. The economic pain lands on Europe, South Asia, and East Asia within days. 3. The Interdiction of Toll-Paying Vessels Is an Act of War Against Third Parties At least two vessels that have traversed the strait paid Iran fees in Chinese yuan to guarantee safe passage. Trump has now ordered the U.S. Navy to intercept those ships. That means American warships boarding or seizing vessels from China, India, and Pakistan — sovereign nations that are not parties to the U.S.-Iran conflict. This is not a blockade of Iran. This is a naval confrontation with the entire Indo-Pacific trading order. 4. The Ceasefire Is Now Dead Hundreds of tankers were still stuck in the Gulf waiting to exit during the two-week ceasefire period — three supertankers had just passed through on Saturday for the first time since the war began. That narrow diplomatic opening, brokered partly through Pakistan, is now effectively closed. By announcing a blockade hours after talks collapsed, Trump has signaled that the U.S. is no longer interested in negotiated outcomes. Tehran now has no incentive to de-escalate. 5. Iran's IRGC Is Already Responding Iran's Revolutionary Guards stated that "all traffic is under the full control of the armed forces" and warned that "the enemy will become trapped in a deadly vortex in the Strait if it makes the wrong move," posting a video showing vessels in crosshairs. The IRGC does not make empty gestures in these announcements. Mine warfare, fast-boat swarms, and anti-ship missile batteries are already pre-positioned. A U.S. mine-clearing operation in contested waters, under live IRGC targeting, is one miscalculation away from open naval engagement.

Things might get interesting if the U.S. Navy tries to stop this ship moving through the Strait of Hormuz.

An important day on the gardening calender - the appearance of the 1st strawberry for the year. Not ready to pick yet though & hopefully there are many others on the way.

@Kallang22 Might get interesting if ships start transmitting false AIS data/positions.

@DiackChris And how will the USN determine if the ship paid a toll & what will they do even if the ship did paid a toll?

@GregAtkinson_jp Bulk Carrier last port Jebel Ali in Dubai. So the only issue is if it pays the IRGC toll for transit passage through the strait. Panama Flagged. PRC owners.

It was just in June last year but it now seems so long ago. I guess I won't be back in Dubai & having a glass of champagne at around 2am for quite some time. youtube.com/shorts/yjE1qZ0…

@MrPatte79195679 It's a complete dog's dinner. What will the US navy do if a ship fails to stop in international waters? Fire on it?

@GregAtkinson_jp Imagine being a fly on the wall in the war room? It's pretty hard to formulate a plan unless you have a clear political objective. Reminds me of another leader in Europe who didn't have a clear objective either.

@Kallang22 According to Donald...at the moment...that is. Then again ships can broadcast false information so the USN is going to have check every ship's past track.

"Resist it while you still can" - before more laws are past to censor or even jail you for expressing an opinion that doesn't align with approved views. Multiculturalism is to nations what poison is to the human body. At first you may not notice it, but after a while it will make you quite ill.

I've spent probably 20 hours or so trying to get a good mesh around a 3D parts model & have not been able to do so. Now after I finally zoom in closely, I can see the small parts that are causing the problems. That's life :)

My Computational Fluid Dynamics (CFD) meshing tip for today is that if the small parts & sharp edges on your CAD model are not needed for your simulation modelling, then spend some time & delete them. I often get lazy & skip this & usually end-up going back & doing it anyway.

@GregAtkinson_jp Tks for the link, finally watched it. Pilmer admits at the end climate is warming but says no CO2/human role. He sidestepped the physics of CO2 absorbing infrared & trapping heat. How did you conclude that CO2 doesn't trap heat, or that adding more doesn't cause further warming?

Climate scam number 1 is that many politicians & public servants travel overseas in business class whilst those struggling in small business need to travel in economy class & still get hit with the costs associated with net zero.

This morning I am reminded that trying to quickly set-up an experiment using computer models, simulation apps & a touch of AI without taking notes can lead you into a whole world of frustration.
