"Researchers at Aalto University published a new quantum theory of gravity in 2025 that describes gravity in a way compatible with the Standard Model, using four one-dimensional unitary gauge symmetries. They're presenting it openly for the community to stress-test. Could be real, could be another dead end but it's getting serious attention."

Researchers have developed a novel mathematical model that treats biological tissue as a fluid composed of elongated, aligned particles to explain how surrounding cellular forces influence the speed and shape of wound closure. The model demonstrates that the structural orientation of cells around a wound actively dictates healing dynamics.

Well that takes a load of my mind - I'm glad we got to the bottom of this!
Researchers @ University of Pennsylvania have confirmed that gravity's strength weakens with distance almost exactly as predicted by the equations developed by Newton and later incorporated into Einstein's theory of general relativity. https://phys.org/news/2026-04-gravity-newton-einstein-cosmic-scales.html #Gravity #Newton #Einstein #GeneralRelativity #TheoreticalPhysics #Physics #Astrophysics #Universe #Galaxies #UniversityofPennsylvania

"The Blob" is a pioneering experimental setup in which a perfect, stationary ball of turbulence is generated at the center of a water tank by firing synchronized water jets. This configuration isolates the chaotic swirling of fluids from boundary interactions, allowing scientists to study turbulence in its purest, undisturbed form.

Exam Time Yet Again
The January examination period at Maynooth starts tomorrow (Friday 9th January), so I thought I’d do a quick post on the topic of examinations. First of all let me wish the very best of luck to everyone at Maynooth or elsewhere taking examinations in the next few weeks. I hope at least that the exam halls are nice and warm! Actually, owing to the Sport Hall being unavailable for this examination period owing to building work, some exams will be off campus; my first exam paper is actually being sat in the GlenRoyal hotel.
Here’s a video produced by Maynooth University to remind those taking exams of some general points about preparation and, most importantly, to look after themselves before during the examination period. It’s directed at Maynooth students but students from elsewhere may find useful tips in it.
https://www.youtube.com/watch?v=-c02JFEBrbs
I completed the last of my revision sessions today but, as the first examination for which I have responsibility is not until Monday 12th, I’ll have to wait to find out how any of my own students have done but let me take this opportunity to pass on a few of my own tips more aimed at students in Physics:
- Try to get a good night’s sleep before the examination and arrive in plenty of time before the start. This is especially important when there’s bad weather that may disrupt travel. It is your responsibility to get to the examination on time!
- Read the entire paper before starting to answer any questions. In particular, make sure you are aware of any supplementary information, formulae, etc, given in the rubric or at the end.
- Start off by tackling the question you are most confident about answering, even if it’s not Question 1. This will help settle any nerves.
- Don’t rush! Students often lose marks by making careless errors. Check all your numerical results on your calculator at least twice and – PLEASE – remember to put the units!
- Don’t panic! You’re not expected to answer everything perfectly. A first-class mark is anything over 70%, so don’t worry if there are bits you can’t do. If you get stuck on a part of a question, don’t waste too much time on it (especially if it’s just a few marks). Just leave it and move on. You can always come back to it later.

Mass isn't fundamental - it's momentum you can't see in a fifth dimension.
New paper: particles are massless 5D objects. Mass = ℏk_W/c (momentum along W-axis).
Time dilation? Reduced W-oscillation when 3D velocity increases.
Entanglement? Particle-antiparticle pairs are opposite ends of a single 5D spinor.
E² = p²c² + m²c⁴ emerges automatically.

Oh wow, rooming with #Einstein, #Hawking, and Tao? 🤯 Because everyone knows theoretical physics and groundbreaking math are best discussed over burnt toast and passive-aggressive sticky notes on the fridge. 🤪 James Watson missed out, but maybe he’s the real genius for dodging the roommate drama. 🏃♂️💨

After Lectures and before Examinations
This morning I did my last teaching session of the Academic Year 2024-5, a revision lecture/tutorial on Computational Physics. It was optional, as this is officially a study break, and was at 9am, but I had about 30% attendance which wasn’t bad in the circumstances. As is often the case with optional sessions, I think the students who came were the keenest and probably therefore those who least needed last-minute tips for the examination, but that’s always the way.
The Examination Period starts tomorrow morning, but most of the students who turned up this morning have their first examination on Monday 19th May which happens to be Computational Physics.
Anyway, now that my teaching is over I thought I’d take the opportunity to wish all students the best for their examinations:
You shouldn’t really be relying on luck of course, so here are some tips (especially for physics students, but applicable elsewhere).
- Try to get a good night’s sleep before the examination and arrive in plenty of time before the start. Spending all night cramming is unlikely to help you do well.
- Prepare well in advance so you’re relaxed when the time comes.
- Read the entire paper before starting to answer any questions. In particular, make sure you are aware of any supplementary information, formulae, etc, given in the rubric or at the end.
- Start off by tackling the question you are most confident about answering, even if it’s not Question 1. This will help settle any nerves. You’re under no obligation to answer the questions in the order they are asked.
- Don’t rush! Students often lose marks by making careless errors. In particular, check all your working out, including numerical results obtained your calculator, at least twice
- Please remember the units!
- Don’t panic! You’re not expected to answer everything perfectly. A first-class mark is anything over 70%, so don’t worry if there are bits you can’t do. If you get stuck on a part of a question, don’t waste too much time on it (especially if it’s just a few marks). Just leave it and move on. You can always come back to it later.

Social media isn’t "democratized" just because people sit in Echo Chambers, surrounded by those who agree and cheer them on. True progress comes from challenging ideas, questioning assumptions, and pushing each other to think, learn, and grow—not from endless back-patting.

Ohm's Law:
V=IR#UTE Definition 2:
“Gravitation is Energy stored within Mass; it is absorbed Radiation and it is Potential Energy.”#UTE Interpretation of Ohm’s Law:
Let:
𝑉 (voltage) represent Gravitation, i.e., the Potential Energy (stored or absorbed Radiation).
𝐼 (current) represent the extended Radiation passing through the Surface at distance r != 0.
𝑅 (resistance) represent the Particulate Motion/inertia resisting the extension of Radiation at the Surface. -

You might know the Beatles song Maxwell’s Silver Hammer. (Not one of their seminal works, one might think.) Is the Maxwell in question James Clerk? OK, not that fun so far, but here comes the bombshell:
The Finnish version of the song is called Paulin Taikakaulin, which means Pauli’s Magic Rolling Pin. Can this Pauli be anyone except Wolfgang? Another physicist! Deep.

This is a really powerful method in #TheoreticalPhysics and #CondensedMatter is particular. It's used to detect #PhaseTransitions and understand the universal properties of #ComplexSystems. Here's how it works: https://www.steventhomson.co.uk/post/rg_guide
