A deformable body is not going to work well with a really rigid material. Physics material seems only can simulate friction? Not sure what you mean. If you mean that you don’t get the correct stiffness, see answers above. Deformation only can simulation elastic? Is it possible to simulate...
For all visible purposes, Einstein's brain seems perfectly normal, if not a little damaged, with nothing that would immediately indicate any great genius. We may not know anything until there's another equivalent genius brain to study; perhaps Einstein can't be compared to average brains. Harve...
Ask a group of people to define "science," and you'll get a lot of different answers. Some will tell you it's a really difficult class wedged between social studies and math. Others will tell you it's a dusty book filled with Latin terms that no one can pronounce. And still others ...
But what makes a person able to do all that? Is it a different, more agile brain? Is it exceptional intelligence? It is it an aptitude for noticing information that other people might consider irrelevant? We'll begin looking for answers to these questions at the logical starting place for ...
You might think scientists know all the answers, but light continues to surprise them. Here's an example: We've always taken for granted that light travels faster than anything else in the universe. Then, in 1999, researchers at Harvard University were able to slow a beam of light down to...
In the 10th century, Persian astronomer (and astrolabe adorer) Abd al-Rahman al-Sufi wrote a book claiming 1,000 uses for an astrolabe. The Persian may have been exaggerating slightly, but in the hands of a skilled practitioner, the instrument could provide answers to many problems. With an...

This has become very necessary as theJoint Admissions and Matriculation Boardhas released the just concluded JAMB results for the 2024/2025 academic session and every student is now free to check online. However, if you happen to be among those that have been searching for answers to [check ja...
The complete opposite is true. I spent most of my time feeling confused and conflicted, one of the reasons which drove me to visit Palestine so fervently. Perhaps there I would find my answers. I will try to write about my experience in the West Bank sooner rather than later....
