Susan, I could really use your help this weekend.
@I,@W+W k]
What is it , John? Another term paper? 6n W5rlA
No, no. This is easy compared to that. My cousin is coming on Thursday.

She has an interview at the college and I promised my aunt I'd look after her. 'D

We are going to the game on Friday, but Saturday I'm on duty at the library all day and can't get out of it. Uh, I was wondering if you could show her around during the day and maybe we can all meet for dinner later. F/\Z#p`?
Sure. I don't have any plans. What kind of things does she like to do?

Actually I haven't seen her for three years. She lives so far away. But this will be her first time on a college campus; she is still in high school. So she probably enjoys anything on campus. f S|E(e v
Well, there is a music festival in the auditorium. That's a possibility. Only I hope it doesn't snow.

They are predicting 68 inches for the weekend. Everything will be closed down then. +x6ZR0I,L p YLh
Well, how about, for the time being, I'll plan on dropping her off at your place on the way to work, around eleven. But if there is a blizzard, I'll give you a call and see if we can figure something else out.
+^;M;wEjg MpK{
Sounds good. Meantime I'll keep Saturday open. We can touch base Friday night when we have a better idea of the forecast.
*c QS.C%M
I hope this works out. I feel kind of responsible. She won't know a way around. And I want her to have a good time. Anyway I really appreciate your help. I owe you one.

No problem. I'll talk to you tomorrow.

I see you are having the fish for lunch. +L6a!z0|,j
That's right. Fish sticks and tomato soup, my favorites. "T\P3iqaF6y'i+A&Z
I bet they were frozen.
J3R}? W
What? ;[5hO7orl)@Z
The fish sticks.
/ga*L$U ]ub [&?
Of course they were frozen. We are hundreds of miles from the ocean. The cafeteria can't afford to fly in fresh fish.

I just mentioned it because an anecdote Professor Chambers told in class this morning.

Which class? v+oS-^2Z I;h
My American social history. It's a lot of fun.
d thl(aP
He talked about fish sticks? 4n @ Q)z*h*S
Not exactly. But he did talk about frozen fish. OK, this is back in 1912, right? It's 20 degrees below zero. And this guy Clarence Birdseye's out ice-fishing. "@&k Z)e@
Where is this, Antarctica? S
j5B |8iv E
No. Massachusetts I think. Anyway he catches a fish and drops it beside him on the ice and it freezes solid.
(g lF0I c{
{m
So? A/z \"jG
So, later at home he thaws out the fish in a bucket of water and it's alive. Of course Birdseye is amazed. But he eventually figures it out that the fish froze so fast that no large ice crystals formed. Z[$e|3}:F2j
What do you mean? /?gY\-MD Bg3y;~
Look, usually when a plant or animal cell freezes, large ice crystals form inside and eventually tear the cell walls. That's what kills the frozen plant or animal. And also what changes the taste of something that's been frozen. But if you freeze something quickly , only very small ice crystals form. So Birdseye invented the process of quick freezing food.
~#JZ%@ }
And that was the beginning of the frozen foods?

At the beginning of the century the railroads were used to haul everything. Powerful railroad barons made fortunes without having to be accountable to the public or considerable to the customers. But cars and trucks changed all of that. And by 1970, the rail industry was beset with problems. Trucks were taking all the new business. And even so the rail industry remained indifferent to customers. Also many regulations kept the rail industry from adjusting to shifting market. But in 1980, the rail industry entered the modern era when a deregulation bill was passed that allowed railroad companies to make quick adjustments to fees and practices. Companies reduced their lines by 1/3 and used fewer employees. They also took steps to minimize damage to product. And to increase their shipping capacity by stacking freight containers on railroad cars. To accommodate these taller loads, underpasses and tunnels were enlarged. The image of the rail industry has changed dramatically. Today companies are very responsive to customers and are gaining increasing market shares in the shipping industry. The railroad safety record is also strong. Freight trains have an accident rate that is only 1/3 that of the trucking industry. Trains also come out ahead of the trucks on environmental grounds because they give off only 1/10 to 1/3 the pollution that is emitted by trucks. And railroading does not wear out highways as trucks do.

This coffee can contains soil from my garden. And I prepared slide samples to show you that it is alive. This ordinary backyard dirt is crawling with microbes. Microbes is not a very specific term. There are hundreds of thousands of different species called microbes. What they have in common is that we can't see them with a naked eye. They are microscopic. Look at this slide. You should see some round cells. Those are yeasts . Yeasts are fermenters. And they are necessary for making bread, beer, yogurt and so forth. Now look for an irregular shape with hairs coming out of it. That's a mold. Molds are decomposers, and they are responsible for the decomposition mycoplastlees. You should also see some protozoa. Some protozoa, like the one causes malaria are harmful to people. A microbic that causes disease is called a pathogen. Finally you should see a lot of squiggly lines. They are bacteria. The oldest form of life on earth. Like these other microbes, bacteria are single-cells. But they are even simpler structurally because their cells do not have nuclear. So I've got about a teaspoon of soil in my hand here. In that teaspoon are about ten thousand protozoa, 200 thousand mold cells, a million yeasts, and probably a billion bacteria.

Q*I B4QQe2Y8Tq.T
Ten years ago the eccentric cyclist peddling furiously through the first snowstorm of the year was a rare sight often captured on film for the evening news? Today however it is estimated that four to five percent of cyclists bicycle year round. The increased popularity of winter cycling can be attributed to the creation of mountain bike and its subsequent imitations. Outfitted with parts more sturdy than those of yesterday, equipped with their more stable bicycles, nothing seems to stop the new breed of winter cyclist. With streets dry and clear on most winter days, many winter cyclists wear running shoes and protect themselves from cold by wearing down-hill-skiing clothes. On wet days cyclists can wear special water-proof boots over their shoes. But for all of its popularity, there is a down side to winter cycling. Even mountain bikes can't withstand winter snow and rain without extensive upkeep. But one bicycle store owner is in the final stages of developing a year-round bicycle with an innovated complete chain cover. With bicycle chains covered, cyclists would need to clean and oil their chains only once every six months instead of once a week. Despite her invention, however, she still advises cyclists to take a taxi or bus when it snowing heavily. Not because the conditions are too arduous for bicycles but because she believes bikers can't have confidence in the people who drive cars on days of reduced visibility.
