P 6: Computer Physics: Transistors (continued)

[SLO: P-10-H-67]

Explain that electronic devices are built from circuits that:

- can act as switches that can convert incoming voltage into binary electrical pulses of high and low (or 1 and 0). This is called Boolean logic and is the basis for converting analogue data to digital data. A 'bit' is the smallest unit of data in computing; either 1 or 0. Eight bits make up a byte.

- these switches can be put into combinations that then allow them to achieve complex logical operations

- transistors are very economical and rapid-response circuit components that function as switches

- with advances in engineering, the number of transistors that can be fit per unit area onto a circuit board has continued to increase dramatically; this has rapidly enhanced computing power

- circuits that maintain their 'state' after receiving an input can be said to exhibit 'memory' since they retain the effect of the last action upon them

- circuit systems that allow for logical processing and memory functions form the basis of progammable electronics

- modern day electronic systems are now making use of 'artificial intelligence'; computer systems that can 'learn' the right/best response to a situation by processing vasts amounts of data

- technologies like AI and computer simulation softwares are allowing physicists to tackle problems that require finding patterns in vast amounts of data e.g. climate predictions, astronomy and seismology

- breakthroughs in quantum physics are causing a new revolution in computing that are enabling computers to make exponentially more logical operations per unit time than with traditional computers

- quantum computers use 'qubits' rather than traditional bits. Rather than relying on transistors to store bits, they rely on materials like liquids at very low temperatures (that then exhibit 'quantum' properties) that under the right conditions can also store memory and 'digitise' incoming analogue data. However a qubit does not only store 1 or 0. It can store many more possibilities at the same time (analagous to having coordinates in 3 dimensions rather than just along the x axis). This is the basis for why quantum computing is much more powerful than traditional computing.

- quantum computers are still in early stages of development, and have to overcome manufacturing challenges such core components only functing at very cold temperatures that are at almost absolute zero

[SLO: P-09-I-01]

Describe the structure of the atom in terms of a positively charged nucleus and negatively charged electrons that go around the nucleus:

- These electrons do not go around in predictable circular paths in the way that planets go around the sun. The electrons behave as 'quantum particles' and their location and momentum at any point in time is governed by probability; one cannot predict the motion of an electron.

- The 'shells' in which electrons 'orbit' refer to the level of kinetic energy the electrons possess; the further the shell is from the nucleus, the more energy the electron has.

[SLO: P-10-J-05]

[SLO: P-10-J-06]

Explain at regardless of whether you travel towards or away from a beam of light at any constant speed, you will always measure the speed of light as appox. 3x10^8 m/s. This is a counterintuitive fact and is a base assumption on which Einstein's theory of relativity is based.

[SLO: P-10-J-07]

State that objects travelling close to the speed of light will experience time dilation. Assume there are two twins, A and B, who begin at the same place on Earth and then suppose A stays on Earth and B goes on a rocket journey at nearly the speed of light. Then if B returns back to Earth after he/she measures to be one year, it could be that he/she discovers that for A and everyone on Earth 70-80 years have in fact passed.

[SLO: P-10-J-08]

Explain that gravitational fields can slow down time relative to objects far away i.e. if there were two twins on Planets A and B, where A was much more massive than B, then the twin on A would age much more slowly than the twin on B. If the twin on A felt that one year has gone by, it could be that the twin on B felt as if 50 years had actually gone by. This phenomenon is explained by Einstein's theory of relativity and is called Time Dilation.

Theory of Knowledge in Physics:

[SLO: P-10-M-08]

Explain 'empiricism' as the idea that all knowledge is derived from sense-experience. Connect this with the philosophical view that evidence from the empirical world is more reliable than mathematical projection.

[SLO: P-10-M-09]

Explain 'rationalism' as the idea that knowledge should take precedent from reasoning, not sense-experience. Connect this with the philosophical view that mathematics is more reliable than the impressions made from empirical world.

[SLO: P-10-M-10]

Differentiate between the philosophical views of scientific determinism (that everything can be predicted through calculation if all the physical conditions are known), indeterminism (that everything occurs as a matter of probability) and theological determinism (that there is a diety or dieties that determine every event that occurs in the past, present and future of the world)

[SLO: P-10-M-11]

Differentiate between reductionism and holism in the context of science as:

a- reductionism as the view that complex interactions and entities can be reduced to the sum of their constituent parts

b- holism as the view idea that all the properties of a given system cannot be determined or explained by its component parts alone. Instead, the system as a whole determines in an important way how the parts behave.

[SLO: P-10-M-12]

Differentiate between positivism and postpositivism in the context of science as:

- positivism is the view of science that holds that every rationally justifiable assertion can be objectively scientifically verified or is capable of logical or mathematical proof

- postpositivism is an amended view of positivism that holds that that theories, hypotheses, background knowledge and values of the researcher can influence what is observed e.g. the cycle of day and night can seem like proof of either heliocentrism (view that the earth goes around the sun) or geocentrism (view that the sun goes around the earth)

[SLO: P-10-M-13]

Explain Occam’s Razor (principle of parsimony) as the belief that the simplest explanation is the ideal one; the one with the fewest assumptions

[SLO: P-10-M-14]

Explain falsifiability as the idea that a theory is scientific only if it makes assertions that can be disproven

[SLO: P-10-M-15]

Explain, with examples, that scientists analyse data and look for patterns, trends and discrepancies, attempting to discover relationships and establish causal links. This is not always possible, so identifying and classifying observations and artefacts (eg types of galaxies or fossils) is still an important aspect of scientific work.

History of Physics:

[SLO: P-10-M-01]

Explain, with examples, that:

a) civilisations across the world have, since before recorded history, studied the workings of natural world.

b) to do science is to be involved in a community of inquiry with certain common principles, methodologies, understandings and processes (these have varied across geographically and historically)

[SLO: P-10-M-02]

Explain, with examples, that a 'scientific paradigm' is a theoretical model of how nature works

[SLO: P-10-M-03]

Explain, with examples, Thomas Kuhn's theory of paradigm shifts in the history of physics

[SLO: P-10-M-04]

Recognise that politics and social inequalities can affect who gets credit for a scientific discovery e.g. historically the contributions of women to scientific research have not been highlighted

[SLO: P-10-M-05]

Recognise that historically 'modern physics' emerged from the field of 'natural philosophy', and today debates about what is physics and what is metaphysics continues e.g. contestations about fields like String Theory since they do not produce predictions that are experimentally verifiable

Conceptual:

[SLO: P-12-K-01]

Describe Earth's climate system as a complex system having five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).

[SLO: P-12-K-02]

Define climate as the statistical characterization of the climate system, representing the average weather, typically over a period of 30 years, and is determined by a combination of processes in the climate system, such as ocean currents and wind patterns.

[SLO: P-12-K-03]

Explain climate inertia as the phenomenon by which climate systems show resistance or slowness to changes in significant factors e.g. stabilization of greenhouse emissions might show a slow response due to the action of complex feedback systems

[SLO: P-12-K-04]

Explain that climate change can be categorised into internal variations and external forcings:

- Internal variability can consist of factors that are either cyclical (e.g. the Madden-Jullian oscillation caused by atmospheric circulation and convection) or random (e.g. the ocean and atmosphere can work together to spontaneously generate internal climate variability that can persist for years to decades at a time)

- A change in the energy budget is called a forcing, and when the change is caused by something outside of the five components of the climate system, it is called an external forcing. Volcanoes, for example, result from deep processes within the earth that are not considered part of the climate system. Off-planet changes, such as solar variation and incoming asteroids, are also "external" to the climate system's five components, as are human actions.

[SLO: P-12-K-05]

Explain how global climate is determined by energy transfer from the Sun with specifc reference to the below factors and terms:

- Recall and use the term Earth energy budget

- Explain how the energy imbalance between the poles and the equator can affect atmospheric circulation

[SLO: P-12-K-06]

Explain that due to the conservation of angular momentum, the Earth's rotation diverts the air to the right in the Northern Hemisphere and to the left in the Southern hemisphere, thus forming distinct atmospheric cells.

[SLO: P-12-K-07]

Explain that monsoons, seasonal changes in wind and precipitation that occur mostly in the tropics, form due to the fact that land masses heat up more easily than the ocean. The temperature difference induces a pressure difference between land and ocean, driving a steady wind.

[SLO: P-12-K-08]

Explain that ocean water that has more salt has a higher density and differences in density play an important role in ocean circulation.

[SLO: P-12-K-09]

Explain how the thermohaline circulation transports heat from the tropics to the polar regions.

[SLO: P-12-K-10]

Explain that ocean circulation is further driven by the interaction with wind. The salt component also influences the freezing point temperature. Vertical movements can bring up colder water to the surface in a process called upwelling, which cools down the air above

[SLO: P-12-K-11]

Explain, with climate systems as examples:

(i) what is a positive feedback cycle

(ii) what is a negative feedback cycle

[SLO: P-12-K-12]

Explain, using the metaphor of a butterfly's wing flaps may cause hurricanes in another part of the world, how climate science is a an example of a chaotic system (mathematics of chaos theory are not required; just the idea that with very complex systems it is very difficult to predict outcomes and they are very sensitive to initial conditions)
