Introduction This is the fifth and final unit in the MSXR209 series on mathematical modelling. In this unit we revisit the model developed in the first unit of this series on pollution in the Great Lakes of North America. Here we evaluate and revise the original model by comparing its predictions against data from the lakes before finally reflecting on the techniques used. This unit, the fifth in a series of five, builds on ideas developed and introduced in Modelling pollution in the Great Lakes
2.9 Summary In this section, I started by emphasising the fact that the computer, which has become more or less omnipresent in modern society, is a tool like any other. I went on to look at the special nature of that tool, establishing that its function is to capture, store, present, exchange and manipulate interesting aspects of the world. I then introduced the idea of two contrasting realms: the analogue world we inhabit and the digital interior world of the computer. When we capture featur

DIEGO VEL Cornerstones: Irish Americans The DPS protein compacts the eubacterial chromosome during stress When an E. coli cell enters into stationary phase, transcription and cell division cease completely. In such cells, the normal chromatin components, such as those described above, are replaced by a negatively charged protein called DPS. The interaction between DPS and DNA appears to be a specialised bacterial adaptation to survive starvation. In normal conditions of growth, the DNA within the bacterial cell is distributed evenly throughout the entire cytoplasm. In stationary cells, how 1.1.5 Clearing the previous calculation To clear the previous calculation, click the 'C' button. Provided that no operation has been performed on an entered number, an incorrect entry can be deleted one digit at a time by clicking the 'Backspace' button. (This is labelled 'Back' on some versions of the Windows calculator.) Introduction People have always communicated with each other – initially by face-to-face communication through gestures and sounds, then over a distance through written messages and signals in the form of fires, lights or flags. Technology, for instance in the form of electrical signals, has reduced many of the limitations of distance. Communication networks have become very important, and modern society depends on them for the smooth operation of economic and social activities.

WGTE Preview: They came for the opportunity. They stayed because they had made a home for themselves and their families. The Irish provided a crucial cornerstone in the building of Toledo. Video is of good quality and good for middle elementary and middle school students. (01:19)
Zan Barry talks about the holistic techniques and trainings for stress management and well-being offered by MIT Community Wellness.
Less than two months after her husband was killed, Mrs. Kennedy made a newsreel tape, thanking the American people for all their expressions of sympathy after JFK's death. The tape was played in movie theaters, before the feature film was shown, and is now maintained in the National Archives.
Look around a school...how many different shapes can you find??? This video takes a tour of a school pointing out different shapes.
We all know the American flag, but how did it come about? Explore the origins of the flag and the history of why we celebrate it on Flag Day. (01:29)
Specific anterior muscles of the leg of a dissected cat are reviewed with proper pronunciation by a professor. Origin, insertion, and functions are given. This would make a great review for students preparing for a cat muscle practical. 3:51 min. Color video with sound.
Interactive simulation demonstrating calculation of area of a triangle
This video from National Geographic gives us a peek at what Manhattan would have looked like when Henry Hudson discovered it. (Professional video that shows scenes of NYC without the buildings, bridges, and such). (01:39)
