Observing and Experiencing our Own Reality:

A detailed 3D geometric model of a 600-cell tetrahedral complex. 1.) Dimensions 1D can be a line - something with length only, no width, no height, no thickness, no depth. 2D can be a square - a flat plane figure with only two measurements - length and width, no thickness, no depth. 3D can be a cube - a solid geometric figure with three spatial dimensions of length, width and height (or depth), occupying space and having volume. 4D can be a tesseract - with four spatial dimensions, […]

After Lectures but before Examinations

This morning I did my last teaching session of the Academic Year 2025-6, an informal revision lecture/tutorial on Computational Physics. It was optional, for the students, as this is officially a study break, and was at 9am, and only a handful of students showed up, but I hope those that did found it useful. 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.

In the past such revision classes have been routine, at least for me, but for some reason the University has taken to locking most of the teaching rooms during the study break. This causes huge problems finding a space to do revision sessions. I really don’t understand this. There are constant complaints from students about the lack of study space, and the response from the University is that right before the examinations they lock dozens of empty rooms.

Anyway, the Examination Period starts tomorrow morning, Friday15th, but most of the students who turned up this morning have their first examination on Tuesday 19th May (which happens to be Computational Physics).

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. You can always ask for log tables if there’s something you can’t remember.

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.

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.

New mathematical model could explain why some wounds heal faster than others

Understanding how wounds heal after injury could be a step closer thanks to a new mathematical model

Physicist Proposes Dark Matter Is Made of Black Holes That Survived Dead Universes

Dark matter could be made of "relic" black holes that survived the collapse of previous universes, a new model proposes.

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.
