Welcome to RQ #213. There's no theme on this one, just some
science-based questions.

Usual rules apply. Quiz ends on Thurday 2016-03-17 sometime in the
evening my time.


Tropical diseases

1. The ebola outbreak last year mainly took place in which three
countries? (1 point each)

2. The latest disease to make the news, zika, is named after the Zika
Forest in which African country?

3. Name either of two mosquitos that are the main vectors for zika. They
are also vectors for chikungunya, dengue fever, and other diseases. You
can give either the scientific name or the common name.


Astro news

4. Recently, two astronomers analyzed the orbits of some distant
Trans-Neptunian Objects(TNOs). This analysis suggested that the solar
system has a planet far outside where the other planets are and even
further away than all currently known TNOs. What name did they give this
hypothetical planet?

5. They suggested a range of masses (in terms of Earth masses) that this
planet is likely to have. What is the low end of this range?

6. A number of solar system objects have had their existence predicted,
but only one of these was based on actual gravitational effects on other
bodies. Which one?

7. Gravitational waves were "seen" for the first time recently by an
observatory named LIGO. Which two states are the LIGO installations in?
(1 point each)

8. The wave that was detected was thought to be from the merger of two
of what kind of object?

9. What does the L in LIGO stand for?

Aedes aegypti, also known as the Yellow Fever Mosquito
Aedes albopictus, also known as the Asian Tiger Mosquito

No one got this one, but some guessed Anopheles. A good guess, but it's
the vector for malaria, which is not a virus. Aedes is the genus you
want for viruses.

Planet Nine -- any form of the number nine was marked correct. Planet X,
though, was wrong. That was what Percival Lowell named his undiscovered
planet, with the X standing for unknown, not a Roman numeral.

10. The range was 10 to 20 Earth masses

Neptune.

Pluto was at one time considered to have been predicted on this basis,
but later analysis showed that the effects the predictions were based on
were due to incorrect measurements. Another object predicted was Vulcan,
a hypothetical planet closer to the Sun than Mercury. It turns out that
the effect used to predict it was actually due to General Relativity.
Ceres (or the asteroid belt) was also predicted, but that was based on
numerology.

Louisiana, Washington

The one in Washington is in the Hanford Reservation, which you may
remember is the site where they made plutonium for nuclear weapons. The
Reservation is actually much larger than the area needed for the
reactors, but it had a very large buffer around it. LIGO is in that
buffer area.

I think Bode's Law fits too many of the planets to qualify as numerology.

Has a black hole ever seen found outside of a neutron star?

All of them. They're two different flavors of collapsed star.

All of them. Being a black hole precludes being a neutron star, or just
about anything else, for that matter.

Until someone comes up with a physical reason for the relationship, it's
numerology. And not all the planets fit it; Neptune is too close to the
Sun. And if they discover Planet 9 where they think it is, it'll be way
too far.

That's not fair. It's a legitimate observation of a physical pattern.

True. And Mercury doesn't really fit either. But that still leaves
Venus, Earth, Ceres/asteroids, Jupiter, Saturn, Uranus, and of course
the planet Pluto. If an explanation hasn't been found than I say it
just hasn't been found *yet*.

Maybe, but most astronomers consider it just a coincidence.

Not sure why you say that, unless it's because of the ad hoc 0 that they
start the doubling sequence with.

If you're going to consider Pluto, then you also have to add in Eris.
That doesn't fit very well either. It's "predicted" to be at 77.8 AU,
but is actually at 68.

At any rate, the best early models for the formation of the planets do
not use Bode's Law at all.

The matching coastlines of Brazil and West Africa were just a
coincidence, because continental drift was an absurdity, until
plate tectonics was figured out. These things happen.

Exactly.

Clearly, if I'm going to propose a mechanism, it has to account for
planets that don't fit the pattern as well as ones that do. But I'm
not. I'm just noting that Pluto fits once Neptune is skipped over.

I imagine you're right about that. And it it's there.
