Einstein's Riddle

Einstein's Riddle
There are 5 houses of 5 different colours. In each house lives a person of a different nationality. Each of the 5 residents drinks a certain type of beverage, smokes a certain brand of cigar, and keeps a certain pet. None of them have the same pet, smoke the same brand of cigar or drink the same beverage.

The question is: Who owns the fish?

Clues:

► The Brit lives in the red house.
► The Swede keeps dogs as pets.
► The Dane drinks tea.
► The green house is on the left of the white house.
► The resident of the green house drinks coffee.
► The person who smokes Pall Mall rears birds.
► The resident of the yellow house smokes Dunhill.
► The resident of the centre house drinks milk.
► The Norwegian lives in the first house.
► The person who smokes Blends lives next to the one who keeps cats.
► The person who keeps the horse lives next to the one who smokes Dunhill.
► The person who smokes Bluemasters drinks beer.
► The German smokes Prince.
► The Norwegian lives next to the blue house.
► The person who smokes Blends has a neighbour who drinks water.
Einstein's Riddle: Hint

Statements 8 and 9 give us definite information, the first house belongs to a Norwegian and the third house's owner drinks milk. Statement 9 together with statement 14 allow us to deduce that the second house is blue. The possibilities for all the remaining assignments are summarized in the following table. Printing this table and crossing off possibilities that can be eliminated using the statements is a good way to proceed.

Chapter 1. Year Dot.

The Earth is very old, the universe is older still. Life had plenty of time to develop.How much time has been available on the Earth, and in the universe, for life to form? Methods of estimation, early and more recent. The Earth is now dated 4.6 billion years by radioactivity; the universe is dated 1020 billion years by observations of star light.

Chapter 2. Friends and Relatives.

All life on Earth is related to a single ancestor. All forms of life are much more closely related than first appearances might suggest. Major differences, even between animals, plants and bacteria, are superficial. The inner workings of their cells are virtually identical. All life depends on the same source of energy, which is the simple combination of hydrogen and oxygen to make water. Life on Earth had a single origin, making the search for it easier.

Chapter 3. Dating the Ancestors.

When a timescale is added to relatedness, life is found to be very old. Historical ideas about the youth of the Earth, some of the earlier beliefs and influential personalities. Recent progress in dating fossils. Scientific distortions such as hypothetical missing links and the Piltdown Man.

Chapter 4. Before the Ancestors.

Life is at least as old as the Earth. New technology enables protein or DNA sequences to be compared, but a fresh argument questions whether this provides a reliable evolutionary timescale.

Chapter 5. Life's Not Simple.

Life on Earth has always been complex. Primitive life more than 3.8 billion years ago was already highly complex, with cells, genes, proteins and an intricate biochemical metabolism.

Chapter 6. Thanks to Thermodynamics.

If life was never simple, how did it start? The central paradox of life: since life can only be complex, how can it ever have been simple? The evolution of life's chemistry happened in the 10 billion years or so before the Earth existed.

Chapter 7. Non-Event.

The moment life did not come into existence. There wasn't one.

Chapter 8. Spreading the Message.

Life is universal - but don't bother searching for it. Doubling processes, such as gene duplication and cell division, are so fundamental to life that a single primitive cell, almost regardless of its inefficiency, could colonise a sterile ocean in a blink of geological time. Ice comets could preserve and transport inter-stellar chemistry. The Oort Cloud and Kuiper Belt are great reservoirs of cometary material that can survive passage through the atmosphere into the oceans of the Earth.

Chapter 9. Unintelligent Design.

Life's inheritance. Life's timescale is at least that of the universe, not merely the Earth. Life has changed very little in the Earth's accepted timescale of 4.6 billion years. Evolution has been merely a few simple variations on an underlying biochemical theme. Innovations have been trivial. Far from the age of the Earth providing any constraint on the antiquity of life, ultimately an understanding of the origin of life may throw fresh light on the historical timeframe of the universe.

Chapter 10. Life: To Be Continued?

Life could do better, but probably won't. A genome is a program for the construction of a living being and we are on the point of being able to rewrite that program to manufacture any grotesque combination. The human species has reached the critical point where it can change its own destiny. On the other hand, human intelligence and social behaviour have changed little in thousands of years and will change little in future millennia

January 2009 courses.itinary,,,,,,,

review: january 2009
Astronomy courses will be presented in PowerPoint. Some of the charts will be in Library Reserves (hardcopy), and Bookstore. The plan is to offer these courses in jan-mar.. (where almost all the charts will be listed). To access courses, visit: website.. In order to access the materials you will need your user name and password then click on url. (This will not work until the schedule is loaded, usually the first day of class)..

Astronomy Lec/Lab PHYS117
Astronomy Lec/Lab PHYS117 for Spring 2009) has two evening astronomy classes. There are also Lecture only PHYS107 that meet on fri-Tu 10:45-12:05 and 4-5:20PM. The t323Lecture/Lab class will require the completion of at least 3 of the 6 labs assigned. Enrollment in the class will be limited by the size of the room (probably 22 to 34), but the Lecture/Lab course size will be limited by our facilities and equipment (17 at present).

The content of the courses will be

PHYS10 11:45 AM Solar System

PHYS11 4:00 PM Deep Sky

PHYS12 Tu 6-9 Solar System

PHYS13 Th 6-9 Deep Sky
Summer 2009 there will likely be a sat-tues 7:45-10:15PM PHYS16 during the beginning (6 week) session. Summer is a great time for astronomy labs! autumn 2009 schedule will be similar,

Due to next weeks prospect of severe weather in all circumstances the latest info will come from instructor.all corespondance if there are different instructions will be posted in foyer notice board.

Throw out all the notes ,

The kinetic energy of an electron emmitted from a photoemmissive surface
is equal to the frequency of the incident light multiplied by Plank's
constant. Plank's constant is named after it's discoverer, John Constant,
who stumbled across the number while playing Keno on a transatlantic flight
to London in 1937. This discovery was somewhat fortuitous for Constant, as
he inadvertantly got on the wrong flight- (He was supposed to flt to
Zurich)

When Constant eventually arrived in Zurich he met a young Albert
Einstein-who was at the time significantly younger than he would be in 2
decades time. The purpose of this meeting was twofold-

1) To redefine the laws of space and time, and
2) To redefine 'Gregory's' top ten list of Europe's finest strip-clubs.

Sharing a genuine passion for advanced mathematical physics, Constant and
Einstein had no trouble with the second of these objectives, however the
listing of London whorehouse 'Tittany's" over Munich's finest Brothel,
elaborately named with typical German wit and flare as 'the designated
establishment abiding by the predetermined council guidelines that allows
men to enjoy a night of efficient German sexual intercourse in accordance
with council regulation 17 tripple x c B 4.' This inavertantly triggered
the second world war, which was fundamental in shaping today's
understanding that there is not one single attractive woman in all of the
Brittish Isles.

The first of these objectives did prove slightly more difficult, and it
took 5 years for the theory of relativity to be developed. However there
was one lingering critical problem- The theory of relativity was incredibly
difficult to understand, inspite of all the publicity concerning the
assasination of JFK. Many people he did try to understand it formed
self-help groups. Einstein once read it out on hospital radio, and no fewer
than 12 people got out of coma's, packed their bags and went
home. Unperturbed, Einstein decided that he would use telephone counselling
service 'lifeline' to get his theory to the world. Einstein talked to 7
people that day, all of whom committed suicide. Einstein usually wouldn't
have minded that much, but one of those was a wrong number- he phoned up to
order a pizza.

Einstein 'passed on' in 1967, incurring a penalty against his rugby side
for breaking one of the most fundamental laws of the game. Furious with the
decision, Einstein ran out to the road screaming, where he was hit by a
truck.

The way the water wends

It's twice the rate at which rain doth fall
Into how fast it's a-gittin' there, square.

Plus what it is a holdin' it back times
Deux points trois ( l'eau sanitaire).

And how far thou art toward heaven
(or toward hell better not go there!).

Now, I ain't the one who made this up,
But I do believe it's true.
And if you want to check it out,
Right here is what you do:

Talk with them fellers, Leon and Dan'l
(They's the ones who told it to me).
Though, strange, when I asked them who they wuz,
They said "Oil her" and "Burn you, Lee!"

Winding along the worrisome way,
Things heat up, and so I guess
You better not forget to
Account for shear distress.

My palpitatin' heart is a-pumpin',
It's plumb positively displaced!
And those heady words, "Energy o'er weight,"
My feeble mind just can't erase.

I'm feeling hot, tired and hammered,
Need a cool shower, I would say.
Ain't got no indoor plumbin' here,
But I figgered me another way...

Got eleven sixty gallon water barrels;
The old horse can lift 'em six feet,
And wash me down in just a minute,
That'll be perfect and complete!

Schroedinger's cat

I have been reading of Schroedinger's cat
But none of my cats are at all like that.
This unusual animal (so it is said)
Is simultaneously live and dead!
What I don't understand is just why he
Can't be one or other, unquestionably.
My future now hangs in between eigenstates.
In one I'm enlightened, the other I ain't.
If you understand, then show me the way
And rescue my psyche from quantum decay.
But if this queer thing has perplexed even you,
Then I will and won't see you in Schroedinger's zoo.
