Making steel brittle | Designing an experiment to show for students in history class

Hey all, I'm new to this sub! Looking for some guidance, since I started researching the topic and it's a bit confusing. I work in engineering education and this semester our students are taking a course called "6 inventions that changed the world." Among those inventions is steel, as a material, how it influenced the civilization and how incredibly important it has been since.

Our students are engineers so even this history class is supposed to include science/engineering basics for them to learn. Me and my team really wanted to make a cool demonstration for them and came up with the following experiment: taking a steel rod and heating it with a blowtorch (?) until it's glowing hot, then dipping in water. As far as I understand, it must become brittle if left without further heat treatment. We break it it half to demonstrate how brittle it's become and then repeat the procedure but after cooling in water we heat it again and cool slowly, in sand for example, and then try to break it again to reveal that it is much more ductile now.

I would like to get some feedback from people who have experience with this. I'm also not entirely sure it will work the way I described, so I would appreciate critique. Thanks a bunch everyone!

Research opportunities at Brno University of Technology as an undergraduate?

I consider applying to study engineering (mechanical or chemical) in a few Czech universities. I wanted to ask what kind of experiences you may have had with doing science/engineeirng research in Czechia as an undergraduate, how open are those opportunities, etc?

My working background is in engineering education, as I've been working on building a brand new Bachelor's of Engineering, which is project-based. I also teach similar stuff in high school. So it is important for me to be very active in my educational journey. I wish to have an opportunity to do research/projects along with studying.

Студентські клуби в Українських університетах

Працюю зараз над партнерством Американським університетом і зайшла мова про студентські клуби і як воно в них влаштоване. В свою чергу хотів рохповісти як це працює в нас, але зовсім не мав такого досвіду в університеті. Можете розповісти як воно в нас відбувається, особливо цікавлять якісь технічні, інженерні ітд.

How rainy is that gonna actually be?

I’m planning a hike on weekends in Franconia ridge, and I use windy.com to check for weather. But I’m not sure of how to interpret this data about the rain.

What weather app works best for planning a hike in white mountains?

I am using windy.com at the moment and I like the interface a lot. But I guess relying on one tool only is a bad idea so what else is put there that I can use?

Planning a hike on next weekends, either Franconia ridge but weather doesn’t seem to be too good. So thinking of changing the location.

Where in the White Mountains, next to the Franconia Ridge can I do dispersed camping far from trails and camp sites? Suggest an area please.

Any film photography fans among you Harvard students?

Hey! I'm coming to Boston in June. I really liked Harvard and the area when I was there in October. Would wanna make some friends, and well, cameras usually greatly help with that lol. I'm into some film photography, but also astronomy, languages, STEM, guitar, and travelling. Can also bring you souvenirs from Ukraine =)

Science or Engineering department? Which one to choose depending on school's strength in both?

Hello! My major of preference is aerospace engineering, and I will be applying to a whole bunch of universities in the US to study this program, or if aerospace is absent, mechanical instead. At the same time, I do consider physics/astrophysics as a secondary option.

My question is: when I am applying to a university that has the sciences/physics department stronger (academically, in terms of research, etc) than the engineering department, and given that I am admitted to that college, would it be better to maybe pursue physics there rather than engineering?

To illustrate what I mean, I realize that is not the best example, but Harvard has certainly got its physics department stronger than engineering. There's only mechanical engineering at Harvard, no aerospace, and I know that even engineering at Harvard is probably more awesome than in many other schools, but still, Harvard isn't the number one school where everyone goes for engineering, unlike their sciences, including physics/astrophysics.

Important note: I do consider a physics degree since I could still get into engineering with it, especially by supplementing my studies with engineering electives, and I would like to pursue research someday as well, just that I plan to have a career primarily as an engineer.
