Norway – MegaPost 2of2

Here’s the second of two sets of photos!

Unfortunately, time has gotten away from me again, and after a blog update every other day, I’m seeing that I haven’t updated in about a month (I had the others queued up and posted automatically).

After Turkey, MS and I flew to Norway.  Unfortunately our close friend was moving out of the country that week, but we met plenty of helpful hosts through AirBNB, and had a wonderful time.

Our basic itinerary was: Take the high alpine train from Oslo towards Bergen, stopping at Myrdal to take a fenicular rail down to the city of Flam, on an inland fjord.  We took a quick boat ride on the fjord before returning to Voss (mmmm, fresh water!) to catch the remainder of the trip to Bergen (this itinerary thus far is called “Norway In A Nutshell” and is part of a package deal).

After a few days in the charming city of Bergen, we flew to Bodø (north of the arctic circle!), caught a quick ferry across to the Lofoten Islands, where we hiked to the village of Å, and stayed in a rorboer (fisherman’s hut, on the water).  We did an excellent scuba dive in Ballstad, and then hopped up to Stamsund where we were able to board the Kong Harald ship – on the Hurtigruten line.  Due to high costs (though using our student discounts!) we cruised up to Tromsø and had a nice few days in this northern university town.

Feel free to ask questions of the photos below, in the comments section, or by email!  Here’s the second of two sets of photos:

Unfortunately, we missed the Viking festival.  :-(

But we did get to snorkel above the arctic circle!  7 mm wetsuit, 5mm shortie, socks, booties, hood, gloves.  About 12 degrees celsius. 

We saw an AMAZING jellyfish.  Picture doesn’t do it justice.  It’s about as tall as MS standing on my shoulders.  Scary!
 

We met locals along the way!

They dine on varied meats:

Our Hurtigruten ship – learn more; it’s fascinating: http://wikitravel.org/en/Hurtigruten
(we stayed on for about 22 hours, overnight.  The entire 11 day journey in the summer (when we were there) currently costs roughly $3200 per person, in the lowest season in a cabin with shared bathroom and without window; want a bathroom and window?  Double the price.  Want standard meals?  Add $200 per day per person.  So yeah, we didn’t spend long on the boat, but it was beautiful, amazing, enchanting.)

As we got off in Tromso we saw these climbers with their crash pads:
 

Tromso’s sewer covers show the city symbol, a reindeer:

Daily ritual of afternoon waffles!  (Brown stuff is awesomely delicious, slightly sweet semi-soft cheese: http://en.wikipedia.org/wiki/Brunost )

Midnight in Tromso, from the bridge, after listening to a musical performance in the Arctic chapel:

Signs.  Can’t get enough:
 

Tromso has an awesome childrens science museum!  Here, you can lift a weight illustrating the weight of carbon emissions on average, for people in their respective countries!

And a Wave Pendulum!  Woo!  Remember my pendulum?  http://www.whereisholden.com/search?q=wave+pendulum
 

Yay for space!
 
And yay for faces!

And apparently they have a slug problem in Norway, because there’s tons of snail-killing kits; this one uses beer!

Where we traveled on the Hurtigruten (2/3rds of the way up the country; note that we scuba dived right where we started on the cruise; well above the arctic circle):
 

Handsome guy
 

We went for a short day hike on horseback!

Sign!

Polar bear, stuffed, in our hotel lobby in Tromso:

Tesla Model S in Tromso, the week they came out there, with a muddy mountain bike (wheels attached) in the back of it.  That car is amazing.
 

In Oslo.  I still think this is an ad for Fanta soda.

Trains that cut through snow / ice in the winter to clear the tracks:

Oldentimes manual train track traverse method!
 
Intriguing wheel design, not totally different than we came up with at Energy Cache!

This South Korean was riding around the world on his motorcycle.  Sweet!  (BMW)
 

Fjord with sheepses:
 

 

Fjords.  Easy to travel straight down, not so easy to traverse.
 

MS with Knute Rockne’s memorial in his hometown of Voss, Norway!

MS with other locals in Voss:
 

Love me some signs.

Please, DO NOT touch the swords (which are for sale)!
 
In-flight airline menu item:

Beautiful islands on the flight north from Bergen!

Come to think of it, yes, it would be cold to drive a wheelchair in Norway in the winter.

Loverly town sign pose.

About midnight at the middle of August:
 

Sign!  Easy enough: Live Cable, Anchoring (your boat) forbidden!

As dark as it ever got for us:

Cod liver oil factory in the village of Å:
 

And fish drying racks EVERYWHERE.  Thank goodness we didn’t visit between January and April when the racks ALLL around town are ALL full of hanging fish.
 

So serene! (Click for lager; email me for full size, or similar ones)

Wave Pendulum

A while back helped a friend, Dan Busby, in building a Wave Pendulum.  I posted a few pictures here, but never got around to posting any videos!  Here you can see Dan and some elementary kids geeking out on simple science!

(Here, our wave pendulum is part of the STEAM Carnival by Two Bit Circus!)

Also, here's a self-made video in a back alley of the wave pendulum, un-cut.

Stephen Hawking's public lecture at Caltech

... in which I freely admit that I only partially understood some of the topics which he discussed, but don't yet admit that his institution (which grew out of Oxford) is any more superior than my future institution.  :-)  Also, apologies for the poor grammar, sentence, and paragraph structure.

Overall, I loved the lecture.  It was accessible to someone who had only read "A Brief History of Time" but also engaging enough for the host professors to comment on new theories in the field.  Loved it.  Professor Hawking also has an awesome sense of humor.

Notes:
Prof Hawking started with a rundown throughout the past few thousand years of humans' understanding of our role in the universe, starting with a tribal group (can't remember where) that believed a typical myth with a main god, who invented the sun, creatures, and stars.  Skipping along, he discussed Aristotle, and then Kant, who held that there are possible universes that exist in space independent of time.  Einstein came along and showed that there is a link between space and time.  Yay.

He discussed that time outside of the universe as we know it is undefined.  It's not that there is no time, or that time would run negative, but more like you couldn't have one without the other (I imagine this as us existing on an X,Y plane, and trying to graph a point with only one coordinate.  Impossible.

He mentioned how if we thought there was a specific start to time, we would probably have to arbitrarily pick it, and then that point would be incomplete, as one moment earlier there would be a lack of information (ie. no space).

He explained that one requirement of a good model was that it gave hypotheses that could be tested and proven true or false.  fuzziness in notes here...   (But that previous point is worth remembering!)

Then we come a bit more into the modern discussion on the origins of the universe, and that the stars are not spread evenly, but formed into galaxies, and that when Hubble first observed the galaxies outside our own, he found a peculiar thing: more galaxies were moving away from us than towards us.  This meant that the universe was not created stagnant and continued unchanging, but rather that the universe is expanding (by observing that the farthest galaxies were moving the fastest).  This means that earlier in time, the galaxies were closer together, and that possibly, they could have been colocated at some "beginning point."

So then people (?) came up with the "Steady State Theory" that although galaxies were, indeed, spreading out, that new galaxies were continually being formed from newly created matter.  Unfortunately, this was proven untrue by noting the uniform radio noise when observing space.

The next theory that came was the Collapse Fail Theory - again starting with the idea that there was no start to the universe, but rather that it was continually expanding (our cycle now) and contracting (just before our cycle now, and will happen again).  The theory says that in the case of a collapse of the universe to a near single point, with a lack of symmetry, the matter in the universe would simply slingshot around the center of mass of the universe and then expand again.  Professor Hawking disproved this, though I'm ashamed to say I don't understand.  He basically proved that asymmetry during collapse couldn't happen.

Then the discourse got lighter for a bit and he joked about the ambient microwaves from space being very ineffective at defrosting our frozen pizzas, as well as joking about his fear of the Inquisition, in light of his presentations at the Vatican (and a bit of a jab at JP2's lack of scientific knowledge [though I think Prof Hawking is allowed to make that joke regarding most other humans on the planet, to be fair]).

He discussed the rate of inflation in Germany after WWI, and how it wasn't such a good thing, but that the rate of expansion of the universe after the Big Bang dwarfed the German currency inflation, and that *was* a good thing.  On the order of one million, trillion, trillion fold within a fraction of a second.  (Turns out that this is related to a second thesis of his "Hawking Radiation" idea, more later.)

Extreme inflation right after the big bang.

We looked at some maps of the universe, which was sweet.

Professor Hawking discussed how General Relativity doesn't cover quantum items, which fall under quantum theory.  Which is fine, except when you realize that the entire universe might be tiny as viewed from the outside, and in that case, our entire universe might follow quantum theory.  So we've got some challenges there, since we think we've got all the items under General Relativity under control / understanding.  To answer this, we learned about Feynman's "Sum History" of universes in which every possibility is indeed possible, but with various weighting for probability.  

Now onto the "No Boundary Proposal" that Prof Hawking and Prof Hartle (UCSB) proposed.  In this, we have a formation of the universe in a Euclidean frame of reference, where there is no time, and simply space on each of two axes.  At some point, this transitions to a Lorentzian frame, where time replaces one axis and we now have the space-time that Einstein helped us understand.  (See image below) The explanation of the Euclidean frame is much like the bottom half of the earth.  If you traveled to the South Pole, you would find yourself at a point.  Now, if someone asked you to travel south, you would not be able to.  Not for lack of trying, or lack of space, but more that there exists no point more southerly.  It's undefined.  Just as the laws of physics hold on our Earth's South Pole, so should the laws of nature hold at the beginning of time, at this space X space frame.

Hartle-Hawking model of Big Bang

He discussed *very* briefly the "M theory" which is a collection of theories that try and answer the deep questions such as "Why are we here", "Where did we come from" and "Why do we have this set of laws, and not some other set of laws."  Lots of multiple universe stuff going on for a minute.

M Theory representation

His closing suggestions:

"Look up at the stars, not down at your feet!  ...  Be curious! ...  It matters that you don't just give up!"
(I like how he doesn't say "don't give up" but instead "It matters that you don't just give up!")

In the Q&A we discussed Hawking Radiation which is the idea that radiation is emitted at the event horizon of black holes, and this is a possible way that the energy escapes.  In a second, later case, Hawking Radiation is the radiation emitted at the horizon of the Big Bang, which would have disturbed the uniform density of all matter to break up into dense pockets that eventually became galaxies.

He mentioned that now that we have matter (mostly) figured out (though he hates being a bit wrong on the Higgs Boson), that we have a grasp on 6% of the universe: the normal matter.  Now we can delve into the 27% of the universe: dark matter, and then onto the remaining 68% which is dark energy.  Whew!

A few other questions about Quantum Entanglement and the Big Bang Black Hole Theory, in which Prof Hawking discussed the necessity of an event horizon to move as matter is consumed (and the fact that nothing could know of this move before it moves, because there could be matter further ahead of you, about go go over the event horizon) as well as killing the idea that matter that enters black holes could somehow be forming other universes (and be a possible source of our universe).

Successful End of Event!
