    Hi, in an outreach project we are currently developing teaching material on particle physics, which will be made available to teachers, free of charge, online and printed versions (see website, in German 🙁 ). For the chapter on the BEH field we would like to reprint your “Mexican hat + nail” figure from http://quantum-bits.org/?p=233. So I am asking for permission to reprint the figure and the requested conditions (e.g. Copyright: Frédéric Bellaiche).

    Thank you very much,
    Uta

    Dear Dr. Bellaiche,
    I am writing a book for grneral public concerning cosmology. I found your description of interactions in https://www.quantum-bits.org/?p=2772 very interesting. May I use your figure?
    Best regards,
    antonino del popolo

      Hi Antonino. Sorry for being late to answer. Yes, of course, you can use this figure as you like.
      Best regards

    Dear Fred Bellaiche,

    I would like to include two of your pictures, which were used in the German book “Teilchenphysik. Ladungen, Wechselwirkungen und Teilchen” (mentioned above by Uta Bilow), published by ‘Netzwerk Teilchenwelt’ and the ‘Joachim Herz Stiftung’, in my master thesis. My thesis addresses students and teachers and the book where your pictures are published to which I refer is also for teachers. So it would be very nice and useful. In case you (and the book’s authors, which I ask separately) agree, I would like to take the German version from the book.

    Thanks in advance
    Yours sincerely
    Lea Debus

    Dear Mr. Bellaiche,

    a few days ago I wrote a message here, but I think my message got lost. So I will try again:

    I really like your Higgs-potential diagrams. They were published in the German book >>Teilchenphysik. Ladungen, Wechselwirkungen und Teilchen<>Joachim Herz Stiftung<>Netzwerk Teilchenwelt<< which can be found here: https://www.teilchenwelt.de/material/materialien-fuer-lehrkraefte/unterrichtsmaterial-teilchenphysik/ (unfortunately in German). In my master thesis I work out a way to understand the Higgs-mechanism with school knowledge. For this it would be very nice and useful, if I could use your pictures of the Higgs potential (and the comparison to the nail).

    With best regards,
    Lea Debus

    Frédéric, I found very useful one of your images in “What’s this Higgs boson anyway ?”. May I use it for my final project of my degree? I will cite your page
    Sincerly,
    Abel

    Nice to find people that enjoy old computers (Macintosh). Anybody, know where buy a flyback transformer for Macinstosh Plus (157-0042c lifon E94167 MFB-2 )? In Spain ?! : (
    Thanks,

    Hi there, great website. quick question, how did you take off the clear window on the tape drive on the CPC 464 ? Also on the tape cassette with a cable and headphone jack – how did you get that to work, and close the tape drive, as the able will stop the drive from closing ?

    Thanks

    Damian

    Hello, this is Axel from Germany. Seems that we have a lot in common 🙂 My first computer was an Apple II+ at my school, too. We had a great time with that Apple. Then I owned my first C64, later Amiga 2000, 4000, Draco and many more. I have now over 45 different computers. But I like emulations, too. So when the Pi and Emulation Station, Retropie and so on were available I had one system for sure. Now I am after Retrobat, which works really fine.
    Why I am writing to you is the fact, that I have biiig problems to start a Mac emulation on Retrobat. I found nothing about it, I tried so many things. Nothing works. Now I have a Batocera image that includes a Mac emulation (minivmac) and it works. But this is only on my stick and I want to have the same emulation for a Retro-Gaming Computer. Well, not only gaming but most of the stuff are games, for sure. I tried to copy all the bios files, did exactly what I could see in the Batorcera image but it doesn´t work. I don´t see a picture of a Mac, there is no hidden system or a non accurate sorted system (sometimes they are all under MESS or somewhere else). Nothing. On Youtube I don´t find any hint to it and to register to the Retrobat forum fails. I don´t know why, the system always says that my mailing adress is not valid. Well, they are, I use them a lot 🙂
    Maybe you can help me out with that because I own a Mac Classic and I would love to have an emulation on my PC. Now I am often somewhere in Europe and like to switch between the old computer systems using Retrobat. It´s fun. I can play my pinballs as well (I have 5 pinballs at home). Retro emulating is fun 🙂
    Thanks for you help.
    Kind regards – Axel
