Now you know what I mean. You might call it something else, but that is the term I like. The point is that Matter and Interactions includes explicit ideas about numerical calculations and this a good thing. Let's face it.
Numerical calculations are just as legit as analytical calculations using stuff like calculus. If a solution gives answers that agree with real life, then it is a good solution. We live in a world of cheap and fast computers such that numerical calculations are a fairly standard solution method in just about every scientific and engineering field.
Students might as well start using them right away, right? But you aren't a computer scientist or a programmer? That's ok, the curriculum uses VPython - a visual module that goes with python that makes numerical calculations mostly painless. And it's not just you. Some students also think that programming shouldn't be in physics courses - but they are wrong.
Modern Ideas ————— What is a modern physics idea? We all know that by "modern" we mean stuff that was figured out years ago. You know, things like relativity and quantum mechanics as well as fundamental particles and the atomic nature of matter. Yes, I know that many introductory physics textbooks. However, they are extra chapters at the end in an already huge book. Matter and Interactions is different. At the beginning, the idea of momentum is introduced as the following: If the object is moving much slower than the speed of light, then this momentum can be approximated as mv.
But it starts off with a useful momentum model that works with the momentum principle. The textbook doesn't wait until those final chapters to introduce this idea, it's right there in the beginning.
Focus on the Basics ———————- I guess this is sort of the same as idea number 1. The first volume of Matter and Interactions is essentially three big ideas. The second volume is mostly just two big ideas. To express the time of the action is indefinite, e. Time signals for Present Perfect Tense are indicated by since, for, this week, up to now, so far, not yet, already, often, once, twice, three times, etc. Meaning : five years ago I have lived in Yogyakarta.
Meaning : five years ago I have not lived in Yogyakarta. Have i lived in Yogyakarta for five years? Meaning : five years ago have i lived in Yogyakarta? Meaning : he should I met.
Meaning : he should not I met. Have you met her? Meaning : do I have to meet her? Meaning : Right now they have arrived. Meaning : Right now they have not arrived. Have they arrived? Meaning : Are they have arrived? Past Perfect Tense Past perfect tense refers to an activity or situation completed before another event or time in the past. It is more common in written English than in spoken English. An action that had happened or was completed in the past before another action in the past.
Time markers that are usually used : after, before, when. Meaning : Ten years ago I have been in this city. Meaning : Ten years ago I have not been in this city.
Had i been in this city for ten years? Meaning : Ten years ago have i been in this city?
Meaning : he is gone out of the room. Had he gone out? Meaning : Is he gone out of the room? Meaning : in the airport they have arrived. Had they arrived at the airport? Meaning : in the airport have they arrived?
Future Perfect Tense The future perfect tense expresses an activity that will be completed before another time or event in the future. The future perfect tense means that an action or activity started or will start and continuous up to a certain point of time in the future or up to the time when another action or activity happens.
An action that will be completed before another event or a certain time in the future. Time markers that are usually used : by this time next week, by June, by next month, by next year, when, before. Meaning : This letter will I send it tomorrow. Meaning : This letter will not I send it tomorrow.
Will I have sent the letter by this time tomorrow? Meaning : Have this letter I will send tomorrow? Meaning : This project will we have finished by the end of this month. Meaning : This project will not we have finished by the end of this month. Will we have finished the project by the end of this month?
Meaning : Is this project will be completed at the end of this month? Meaning : Her study will she have finished by this time next month. Meaning : Her study will not she have finished by this time next month. Will she have finished her study by this time next month? Meaning : Is she gonna finished her study by this time next month? This tense is a combination of past and future perfect in one sentence.
Some of these are part time in the future that are related to the time in the past. Could to talk about the things that can be done in the past but was not done or was not successfully done. This tense is used to declare a supposition this is not likely to happen. Because of the requirement that it is definitely not met. Tense this just serves as a shadow only if their conditions are met in the past. Meaning : He is gonna working. Would he have worked?
Meaning : Is he gonna working? Kardimin, M. Pratical Complete English Grammar. Present Perfect Continuous Tense Present perfect continuous describes actions or situations that began in the past and have continued to the present or are still true in the present.
This tense emphasizes the continuous nature of the activity. It does not normally occur with repeated actions. An action quite a long action which began in the past and has continued to the present. The action or state has not stopped at the present time. Time markers that are usually used : since, for.
Meaning : I just have been swimming. Have i been swimming? Meaning : Have I just swimming? Meaning : The rain just blow over. Has it been raining? Meaning : It is raining just let up? Meaning : They have been asleep.
Meaning : They have not been asleep. Have they been sleeping? Meaning : Have they been asleep?
Past Perfect Continuous Tense The Past perfect continuous is used to refer to an action or an activity that continued up to end after a point of time in the past. The past perfect continuous tense is also used to refer to an activity that continued or up to and after a point of time when another action or activity happened. The past perfect continuous emphasizes the duration of an activity that was in progress before another activity or time in the past.
This tense also may expresses an activity in progress recent to another time or activity in the past. Meaning : I have been asleep all day. Meaning : I have not been asleep all day. Had i been sleeping all day? Meaning : Have i been asleep all day? Meaning : Its rain all day. Had it been raining all day? Meaning : Is it rain all day? Meaning : He is been asleep for an hour before they get here. Had she been sleeping for one hour before they arrived? Meaning : Is he been asleep for an hour before they get here?
Future Perfect Continuous Tense The Future Perfect Continuous Tense emphasizes the duration of an activity that will be in progress before another time or event in the future, this is use the future perfect continuous to describe an activity leading up to a time in the future. An action that will be in progress before another time or event in the future. An action that emphasizes the continuity of a future achievement. Meaning : They have lived in this hotels for ten years at the end of this week.
Will they have been staying in the hotel for ten days by the end of this week? Meaning : Have they lived in this hotels for ten years at the end of this week? Meaning : He is gonna stay here for five years at the end of this month. Will they have been living here for five years by the end of this month? Meaning : Is he gonna stay here for five years at the end of this month? For example, because of their sensitivity to rising tem- peratures, polar organisms could offer an early glimpse into phenomena that may occur in ecosystems throughout the world.
The diminishing health of polar organisms and ecosystems is already impacting the daily lives and health of the indigenous people of the Arctic. Therefore, it is important to learn more about polar biology and to communicate what is being discovered widely and rapidly. Efforts to educate the public about polar science could be targeted at a wide range of lay and scientific audiences. The key mechanism for reaching nonscientists is the mass media.
To reach young people, science texts used in secondary and university-level education have to include information about polar organisms and ecosystems. They should convey both the excitement of the polar environment and the relevance of the polar regions to pressing questions, ranging from insights into how bio- molecules like proteins work, how new types of adaptive traits arise, and how global climate change disrupts the functioning of individual organ- isms and ecosystems as a whole.
This same sense of excitement and challenge has to be conveyed to the research community in order to attract to polar science the types of expertise needed and a next generation of creative minds.
There are three general target audiences that could be reached through educational and outreach efforts: 1 K and college education, 2 the research community, and 3 local communities in the Arctic region. Although a text devoted to polar biology might not be suitable for introductory-level classes, upper- division undergraduate classes and graduate seminars might be excellent contexts for presenting the information in such a book or monograph.
Technology exists for transmitting in real time or recording for later presentation the field studies being carried out by polar biologists. An example of how this technology might work is provided by the real-time transmission of activities on oceanographic vessels, for example, the activities of manned submersibles and remotely operated vehicles ROVs.
Live contacts with the scientists participating in these expeditions have proven to be an exciting and educationally successful mode of communicating science. Field expeditions to the Arctic and Antarctic for teachers and students allow them to see first-hand what polar organisms are like, how they interact, and how they are studied.
Web sites could provide attractive, informative, and up- to-date exposure of new audiences to polar biology. A successful model is the web site for the National Oceanic and Atmospheric Administration's Ocean Exploration program, which featured real-time images and "log" updates by scientists during the first biology exploration of the deep Canada Basin in September Provision of curricular materials that can be downloaded from a web site could improve the instructional value of polar biology.
If the media are to present increased coverage of polar biology, then polar biologists must fully engage existing university and other institutional resources for contacting the media and explaining why their work merits press, radio, and TV coverage or assume that burden directly. Training and media programs such as the Aldo Leopold Leadership Program also teach academic environmental scientists to communicate to the public and media effectively and offer another means of training scientists and their graduate students to inter- act with the media.
The Antarctic integrated biology course that was offered for six years in the Crary Laboratory at McMurdo Station might serve as an appropriate model. One of the many strong points of a course of this type is that the participants comprised a wide range of intellectual interests, such that disciplinary boundaries were surmounted very effectively. Many scientists are apt to regard work in polar regions as logistically complicated, inconvenient in terms of time requirements, and "not worth the effort" involved.
To provide an accurate portrayal of what is involved in doing research in polar regions, workshops should be held to familiarize potential polar investigators with the requirements and opportunities for polar work.
Included in these workshops should be a statement of the opportunities that exist for winter season work at polar laboratories, notably at McMurdo Station, where excellent research facili- ties generally lie idle during the winter season.
Although symposia on polar topics often occur within larger meetings, relatively small meetings focus- ing on polar biology that are attended by scientists at different career stages and from many countries could be an excellent vehicle for educat- ing polar biologists about the activities of their peers.
Two examples to build upon are the GRC on Polar Marine Sciences held biannually and a recent symposium supported by the Nordic Arctic Research program that gathered 20 Nordic graduate students with 20 pan-Arctic senior scientists for an educational retreat on Arctic ecosystems in Sigulda, Latvia. Principal investigators who are currently conducting polar field research should be encouraged and assisted to bring collaborators to the field sites. At a minimum, such visits would improve the collaborators' understanding of the biology under study.
Such visits might also lead to increased involvement of the col- laborators or their students in field work. A federally funded fellowship program for postdoctoral researchers could facilitate the entry of new investigators into polar research.
This program is currently under design at the National Science Foundation. NSF has an existing program that offers support for new investigators in polar science.
