Something that I consider very silly, yet I try to solve relates to the relativity of simultaneity. According to SR , two evevnts taking place in different positions along the line of relative motion of two inertial observers are not simultaneous in both frames. Now, I wanted to see how this...

Hello, I want to learn how to create virtual labs (html5, java and on) for physics education purposes. I could work on my own, but I am more interested in getting a solid background from experts. Is there any online course in which I could enroll? Thank you

I am a rather bad case for answering this as my work is mainly focused on designing educational scenarios on STEM and doing teacher training. So I do Physics more or less most of my time :-p To draw the students' attention to Physics I try to find something that intrigues them and then forge...

thank you

Thank you very much. It seems to be exactly what I am looking for. Do you happen to know if similar opportunities exist in Europe?

Hello. I am a Physicist with MSc in Experimental Particle Physics and for the last 3 years I work in the field of Science Education as a teacher trainer, and developer of inquiry based, ICT enhanced educational content in the field of Physics for K12 students in the RnD department of a school in...

Hello everybody. I am involved in a project aiming to address Physics Misconceptions regarding Sound through the creation of virtual musical instruments. One of the major student misconceptions I have found in bibliography is the fact that students perceive sound pitch and loudness as being the...

This means that in a Higgsless universe you would not have 3 neutrino flavors also?

Perhaps there is another way to depict it but you need to know some physics first. Assume that you have a spinning wheel rotating at constant angular velocity (ω). Now, if you start acting on it with a tangential force, then it starts speeding up. Its angular velocity increases with time...

The relativistic increase in mass is due to the fact that at high speeds (u->c) the mechanics you use are relativistic. The term invariant mass is the correct one - a question: how would you define mass in a proper textbook format? E.g I would say that mass is the energy of an object observed...

By "do that" you mean increase the effective area in such a way that you could observe astrophysical signals? First things first: When one tries to do neutrino physics without accelerators or reactors, (or geoneutrinos =>just saying for completeness) the possible signals come from the...

Not quite to me, even though we should agree that this is just a matter of terminology. E.g SNO, or Super Kamiokande cannot be referred to as neutrino telescopes since they cannot observe astrophysical sources of neutrinos ( it is just solar neutrinos and atmospherics ). A neutrino telescope...

Hello, I am opening this thread so as to discuss if possible what you believe is the science case of building a neutrino telescope. Being a fanatic in the field , I would like to hear opinions from whoever wants to say about whether it is important to build such a detector and why. Thank you!

Sorry, but the Kaon reaction you write doesn't conserve electric charge

About the GZK cutoff, yes it exists (or so we believe) which prohibits us from observing protons more energetic than 6*10^19 eV (taken that the interaction length of the proton in the CMB is lower than the proton source- Earth distance). Of course, there might be a way for a (e.g)10^25eV proton...
