I agree that the WSJ statement is very misleading, but I believe they meant it in comparison to Q1 2014, not in comparison to Q4 2014. From the WSJ article: "Profits [...] advanced 3.1% in the first quarter of 2015 from the fourth quar

Is this meant to be a link to the doodle? https://g.co/doodle/3p3jdj If so, as a geophysicist, I approve! :)

Comments like the granparent's frustrate me. Often they're from people who have good reasons, but I feel that it paints a skewed picture. I have a PhD, but am no longer in Academia. However, I think the "systematic" pro

Actually, there's not a simple relationship between magnitude and intensity. Surface wave amplitude depends on a lot more than the size of the earthquake. (e.g. rupture depth, surficial geology, etc) Moment magnitude is broadly calib

Closer to 30 times actually. Moment magnitude isn't base 10.

There are kids that wear button-up shirts and carry briefcases to class?? ...I think we went to very different schools... That having been said, this could make for a really interesting and thought-provoking pen-pal-type program. In partic

While I agree that programming attracts a lot of people that aren't in it for the love of the craft, I disagree with most of your sentiment. I see a creative person who struggles with having to focus on someone else's agenda. Mos

At least looking through sopython, with the exception of today, it's an average of 1 every ~20 minutes during "peak" hours. There are deliberately fewer today, due to the room's discussion of them this morning, but have

Huh, I didn't see that discussion before I wrote the comment, but I was specifically referring to sopython. They mean well, but it does feel a bit like a mob at times.

First off, a caveat: I'm about to complain about a lot of people I respect and rather like. I'll probably take a lot of heat for it, but it needs to be said. I feel like a lot of the closing of niche questions these days comes fro

Sorry, I should have been more clear. They have to be aligned linearly parallel to a line going from Central America to Southeast Asia. If they were aligned any other way, you wouldn't have a fast axis in any particular direction.

Lines pointing across the plane. Otherwise there wouldn't be a fast axis.

They mean that there's a preferred lineation to the individual grains. Consider cutting a sphere out of something similar to this: http://minerva.union.edu/hollochk/c_physicalgeology/images/L... You can

One of the things I found interesting about Iceland is that, at least when I was doing fieldwork there (~12 years ago), beef was outrageously expensive, but lamb and salmon were relatively cheap. We "had" to eat a lot of lamb and

In addition to the libraries discussed on the linked page, have a look at Shapely: https://pypi.python.org/pypi/Shapely if you're not already aware of it. It's GIS-oriented, but in practice, it can be very us

Each image is a different band. Landsat imagery is multispectral imagery. For Landsat 8 data there are 11 bands and for Landsat 7 data there are 8 (if I recall correctly?). Each band is typically distributed as an uncompressed, 16-bit ti

First off, you need to realize that the landsat program goes back a _long_ ways (the first generation was launched in the late 70's). Have a look at the Wikipedia article for more details: http://en.wikipedia.org/wiki&#

Definitely interesting and a neat paper, but please keep in mind that this is _very_ speculative. (However, the authors do a nice job of stating that, and give plenty of specific tests that could be performed by Curosity or a similar rover

On a side note, while the visualization at the start of the paper is quite nifty, does the rotation make it annoying to read for anyone else, or is that just me? Also, from a visualization standpoint, it's an interesting and original f

Great question! In a nutshell, it's because we choose minerals whose crystal structure can only bond with the original element and not with it's "daughter" that's produced after radioactive decay. For example, Urani

I agree, the ageism implied by the OP is rather disappointing. I'm relatively young (mid-30's), but the persistent implications that anyone over 40 is technical inept is rather infuriating. Supreme court justices are (hopefully)

Fantastic to see!! As much as I hope things like this will be a tipping point for python in the scientific community (from a major player to the dominant player), monoculture hurts everyone. Fortunately, one of the great things about ipytho

On a completely unrelated note, is M.S. work in the CS world really: "fully supervised research work done in total peonage with little to no original input"? For us, an M.S. thesis was supposed to be largely independent, publishab

If you can improve on current gravimeters, it should be marketable. Potential fields surveys are still a big business with a lot of customers. (As an exploration geologist in the oil industry, I use gravimetry on a daily basis.) Generally s

For what it's worth, just directly measuring changes in gravitational acceleration is much easier and much more sensitive to changes in mass distribution. We've been able to measure gravitational acceleration very precisely for ov

That depends on the field. At least in my field, doing identical work in industry starts at 100k, while a postdoc salary would be 35-40k. Which one is the "market" rate?
