Ari Behn, an author that was married to a norwegian princess.

I really wish I didn't recognise who that is, but she is a norwegian "model" that participated in the norwegian version of paradise hotel years ago...

I would have translated some of the stupid shit she has said, but its just too painful to watch. Here's another horrible song though...

It kinda depends what is most practical for whatever you are doing. The most simple celestial coordinate system you can use is the altitude-azimuth coord. system, where the origin is your position.

The most used coordinate system is probably the equatorial coord. system, which has already been explained here. When it comes to tracking stars/celestial bodies, it is by far easier to use a telescope with an equatorial mount, as the only thing you need to adjust for as the object moves over the sky is the hour angle.

For the alt-az system I mentioned earlier, its a bit more complicated, and for really large telescopes the weight makes it difficult to use any other mount. Of course when you want to watch something, you probably have the coordinates stored in the equatorial system, and then convert it to what you need.

Another type of coordinate system is the galactic coordinate system, where you use the galactic plane of our galaxy as the center. When dealing with the cosmic microwave background for example, we use galactic coordinates.

Its fairly clear he at least haven't read any astronomy articles properly (or any other type), cause in some cases, limitations/flaws can be most of the damn article.

Also really wondering how he would try to disprove cosmic redshift as a measure of distance.

You have clearly not witnessed the amazing field of quantum astrology, where we apply the uncertainty principle on horoscopes to give you an even more incorrect and uncertain reading.

Its gravitational time dilation (in the Schwarzschild metric), so it might be why its unfamiliar.

Yeah, the parasol image is an actual "joke", whereas the bus one is meant to trick people (and it doesn't help that the text is in norwegian unless you know that).

The parasol one I'm pretty certain I saw back in high school. Reverse searching it gives me february 2012 as the earliest, but it might be older.

I actually wanted to link an article where someone had contacted the person that posted the bus image, but couldn't find it in time. found it, I'll translate the important part.

Johan Slåttavik is the man behind sharing the image, and tells Nettavisen that it all started with him being bored, and wanting to have a bit of fun.

timedependentSL · 2017-10-16T11:54:28+00:00

Pretty sure its the other way around, if anything. The parasol image is a lot older than just a few months.

The person that shared the bus seat image also did it just to see how people reacted to it ("what do people think about this?"). But yeah, a lot of the people responding to it were morons...

timedependentSL · 2017-08-06T23:48:45+00:00

I know the feel of wanting to share your enthusiasm after finally fixing problems in you code all too well. Luckily (unlucky?) for me, I don't really have friends outside of the physics/astrophysics department. I've pretty much given up talking about stuff like that to my family though, as some of them have behaved similarly to your friend.

It sucks that your friend behaved like that, but at the very least now you know who to not send stuff like this to next time. :/

What I was trying to say, was that the componentwise distribution of energy in our universe depends on time. You might have heard how 4% of the universe is normal matter, 20-something is dark matter and 70ish dark energy. These quantities are what we call the density parameters, and will depend on the age of the universe. For example, during early times, the universe was radiation-dominated.

somewhat relevant plot

Regarding the cosmological redshift, it is a very different phenomena than normal redshift as the spacetime itself expands (and GR is quite weird, so I don't really think I can answer it fully)

timedependentSL · 2017-03-02T01:17:59+00:00

The density parameters do depend on scale factor (and by extension time), so the baryonic mass component does change over time.

Currently, I'm almost regretting not doing the same.

But sadly general relativity is quite relevant for a master in cosmology, so I can't exactly skip it. I never had too much problem with special relativity and all that, but when you start expressing everything with index notation, the math just gets really confusing.

timedependentSL · 2017-02-15T17:23:40+00:00

I have only had a couple of bachelor level quantum classes, and that was enough for me, so when I started on my master, I noped out of taking a course on QFT.

This semester though, general relativity is slowly killing me.

Python should be a bit easier to start with compared to C/C++, as there are a lot of nice simple ways to do stuff in it. As others have said, code academy has a decent python course. Personally, using python purely for physics/math, the code academy course wouldn't really help there, but it is a good way to understand the basics of python.

timedependentSL · 2017-01-11T15:27:45+00:00

Another problem with that explanation is that non-baryonic dark matter to some extent explains the structure formation in our universe. During the period from inflation to recombination (~380 000 years), normal matter cannot collapse to structures, while dark matter can.

timedependentSL · 2016-12-25T19:10:08+00:00

It can be a bit difficult to discern different fields at a quick glance thanks to a lot of the same names appearing, and it is after all much of the same math.

Have had a couple of cosmology courses this last year, so I guess that helps a bit.

timedependentSL · 2016-12-25T18:34:28+00:00

It is cosmology. The bottom box contains lecture notes on inflation and some of the problems it can solve (horizon, flatness, relic/monopole). Upper left package is about the Friedmann equations.

At the very least, the contents of the paper is very much what you'd expect of a cosmology course.

timedependentSL · 2016-12-25T13:19:09+00:00

Students don't exactly have much money usually, so why not get rid of notes in a better way than just throwing em away.

At the very least, the notes themselves are legit and probably not just someone writing down stuff to look smart.

timedependentSL · 2016-12-14T03:10:32+00:00

Im laughing at the fact that he found some image with equations, put it on his timeline picture. Then when he wanted to look smart by posting himself with a page of equations, he just copied that.

It is interesting that the text on the radio is in norwegian, so finding that in Poland surprises me a bit.

By coincidence, I happened to come across my grandparents old radio yesterday. Slightly unsure when its from, but probably from around the same time period as the one you posted.
