| Posted: 24 Jun 2017 06:44 AM PDT Heavy diesel engines (buses, construction equipment, transport trucks, etc) particularly tend to be left idling for long periods of time between uses. What's the rationale behind this practice? [link] [comments]  |

| Posted: 23 Jun 2017 02:44 PM PDT Unless the rovers that we sent to Mars were 100% Sterilized before they were launched, wouldn't they have carried with them lots of microorganisms, even ones that could eventually evolve into more advanced life forms? [link] [comments]  |
| Do animals acclimatise to heat in the same way humans do? Posted: 24 Jun 2017 02:09 AM PDT I understand that the human body acclimatises to heat over a period of time, but do animals such as dogs and horses undergo the same changes? If I take my dog to a hot country, will his body make the same physical changes as mine in response to the change in climate? [link] [comments]  |

| Posted: 23 Jun 2017 08:41 PM PDT I have played around a bit, and I feel as though I have an expression that does what I want. However, I can't check it. Is there a established equation for da/dT? [link] [comments]  |
| Would LIGO signal change for merger of larger black holes? Posted: 23 Jun 2017 04:56 PM PDT Would the signal picked up by LIGO from the merger of two moderately large black holes (1,000 suns each to pick a number) be the same only larger, or would it convey additional information not obtained by the signals so far?

| Posted: 24 Jun 2017 05:15 AM PDT The 45/46 number is meant to account for the XX / XY difference and the chimp DNA number comes from here: http://www.sciencemag.org/news/2012/06/bonobos-join-chimps-closest-human-relatives If this doesn't come down to semantics, I will be surprised.

| Why isn't there smoke after a lightning in the sky ? Posted: 23 Jun 2017 09:12 PM PDT As I understand , lightning happens when oppositely charged clouds of particles come in contact generating light and sound. We know that lightning carries a huge amount of voltage , hence current and heat. My doubt is , when the clouds of particles collide, woudn't the burning of various gasses in the atmosphere cause significant smoke and why don't we see smoke in the skies after lightning ..? Thankyou in advance [link] [comments]  |
| Posted: 24 Jun 2017 04:40 AM PDT We all know the periodic table, but exotic atoms such as Muonic Hydrogen, Positronium and Muonium dont have a place in the periodic table. Of course, it would be tedious having a table full of thousands of theoretical atom varieties with one electron switched with a muon or tauon etc, but why not those exotic atoms we have already synthesized? If muons and tauons have more energy and (mass?) & (size?), wouldn't they take up more slots which would give the exotic atom a distinct chemical property? [link] [comments]  |
| How does having "extra" (more than needed) satellites make GPS more precise? Posted: 24 Jun 2017 03:23 AM PDT I understand that 4 satellites are required to calculate a position. Makes sense. But how does receiving the signal of more satellites makes the calculation more precise? How do we know, which signals are better than the others? How is decided which 4 or many possible combinations is used for the calculation. Or how else is dealt with over determined equations for the position calculations? [link] [comments]  |

| Are there or have there been cultures where general sexuality isn't considered something "private"? Posted: 24 Jun 2017 02:50 AM PDT In my impression it seems that sexuality in "modern" cultures is either something very intimate between people or when it happens "in public" it is most likely a special turn-on for the participants and/or observers. A simple example is a couple being intimate in a public place without the explicit intention to be caught or as another extreme example a swinger club where people explicitly want to be watched. Anyway, these things are considered taboo in all cultures that I know. But are there or have there been cultures where it is/was completely normal to engage in sexuality in public without it being something considering kinky by the rest of the society? Some cultures in the jungle or islands walk around naked. No big deal for them. In most "modern" cultures one would get arrested. [link] [comments]  |
