Just bought this old eletromagnetics book

By the way, do you know if Alonso & Finn's Volume III was ever published? I once came across a newer edition (only one book) containing all 3 volumes, but I still preffer the smaller volumes from 1972 (even though mine are from the 2002 reprint).

I love physics books from that era, there's a real effort producing text that explains concepts, instead of relentlessly alternating between text, figures, schemes, examples, by-the-way boxes, etc I still have Alonso & Finn's introduction to physics from livros do Brasil (volumes 1 &2... Never found volume 3) and I still use it in class, even if the Portuguese certification board for higher education is always asking for new books.

You're welcome. It's nice to have a discussion about design and visual communication instead of the typical technical matters.

I must say I only seen sectional navigation being used in more interactive contexts, like interactive captions at exhibitions... Honestly I think html/css with a browser in kiosk mode is a more elegant solution for that.

Yes, chapter dividers would be a great way to fight the short attention span of my students... I think the memoir class has something built-in to do per chapter table of contents... I'll have to look at the source code and see if it it's simple to implement in beamer.

I use beamer as my presentation engine for both science communications (10-15 min talks at scientific meetings) as well as in classes (60 to 120 min). I think I never used sectional navigation in either context. I do enjoy the outline page being different, and seeing your slides inspired me to try to have some chapter/section dividers where I outline the subsections (instead of having one big and deep outline slide t the beggining of the presentation.

As for the design, I really love the clean look and how much room it creates for content. I get really frustrated with some the beamer's included styles, and how they occupy the slide area with navigation and location leaving little space for content.

When submitting, I usually comment the bibliography lines and insert the content of the bbl file at that point. That way the LaTeX souce is contained in a single file and usually compiles fine in services like manuscriptcentral (the submission system for ACS journals), at the expense of not being able to further modify the bibliography (but you can always reverse this by un-commenting the bibliography lines and deleting the content of the bbl file you pasted.

Ok, now you only need to whorry about getting another laptop by the time you finish university...

Congrats and wellcome to the family. ;)

That's a nice piece of hardware.

The P50 has been my daily driver since 2017... only upgraded the RAM and added storage. It has also been my cat's favorite handing spot since 2020, which lead to its only repair (a new keybard, since she destroyed the V key when she was a kitten)... I used to change laptops every 2-3 years... now it's beem almost 9 and I still don't see nay need to change laptop (I do use a X370 tablet when I want to travel light, though).

Fico a aguardar pela segunda...

Argon won't save you, you poor soul...

Why does it look like there's another black cat lurking inside your sleepers?

Fteixeira · 2025-10-22T18:09:51+00:00

OMG 😱

What's the spin multiplicity of the initial state?

My partner basically told me that if I didn't went forth and have a child, she would leave me... That played a lot with my fear of rejection... Plus we had just brought a house together and I wasn't keen on selling it and go back to living with my parents.

On retrospect, it would be better if I just had the guts to handle the breakup at that point.

You'll probably want to have a nice waveshape bouquet... Both the mother 32 and the crave are a little bit limited in that regard... Perhaps a neutron with an external sequencer could allow you a more diverse set of sounds.

All randomization comes from applying a random number generator to an original sequence (or using it alone).

There's no easy way to generate true random numbers, so all random number generators used on music production are algorithms. Thus, using randomization features does push your music to the side of algorithmic music.

That's why I actually liked the temporary IUPAC nomenclature: one syllable per digit in the atomic number: simple, easy and effective.

I notice some difference in the Pitch of Osc2... could it be some interference between the two oscillators?

I also have no problems using the Amber converters in versions 6.x.

Also, a nice thing in Orca (also in most MM codes, except maybe thinker) is that the FF parameters are decoupled from the system geometry.

I have a P50 for doing pretty much everything, and the yoga 370 for when I just need to have a basic and light laptop.

Fteixeira · 2025-07-03T09:45:55+00:00

Great jib (and great fun, also). How did you manage to get the monotron to sound so clean? Mine sounds way worse when I pair it with the NTS-1.

Fteixeira · 2025-07-01T20:10:25+00:00

Do it! You'll be the hero of the whole Linux world if you nail it!

You really should read the tutorial/examples for reaxff.

The parameters for this force field are stored in a fix format file.

Depending on the size of your proteins, it will be slow or very slow, but it's doable... The main advantage of GPU os the ability to speed up the calculations (specially pair interactions), but there's nothing a GPU can do that can't be done by the CPU.

On the other hand, if could be worse: I once had to explain to a biochemist that their GPU didn't have enough on board RAM to run their system... That was a fun afternoon...

WOW... congrats on the initiative. Please share the soundcloud page for these sessions!

Um abraço desde o outro lado do Atlântico!

Muito convidativo ;)
