Salaries for US Graduates (reality vs expectations)

Source: ZeroHedge, Jun 2019

Bushy-tailed and bright-eyed, the average Generation Z undergraduate expects to make $57,964 one year out of college, while the national median salary is $47,000 for recent grads with bachelor degrees who have between zero and five years of on-the-job experience,” Clever writes, concluding that many students have “seriously unrealistic” expectations for their early career salaries.

The Financial Services Sector Earns US$11T annually

Source: Investopedia, Mar 2015

The McKinsey Global Institute also suggested that retail banking, life insurance, and property and causality insurance make up approximately 60% of total financial services sector sales. It can be extrapolated from that estimate that the total revenue of the global financial services sector in 2011 was roughly $11 trillion.

To figure out what percentage of the global economy that $11 trillion represents, a total estimate of global GDP is required. The International Monetary Fund(IMF) estimated that the total global economy was worth $77.6 trillion in 2014. If global financial services kept up its 6% growth rate for the years between 2012-2014, then its 2014 figure would be $13.1 trillion.

Using these 2014 figures and calculations, the financial services sector comprises about 16.9% of the global economy, as measured in GDP. Further data from the IMF shows that the total service economy makes up about 60-65% of total global revenue. If the OECD‘s suggestion that financial services are between 20% and 30% of the total service market, then financial services would comprise between 12% and 19.5% of the total global economy.,

Learning to Learn

Source: Bob Sutton website, Sep 2010
  1. Adopt a growth mindset:
    This might be the most important of all; as Carol Dweck’s wonderful research shows, when people believe that their intelligence and abilities are malleable rather than fixed, they try harder of learn more.

  2. Sleep Well
    Sleep deprivation makes people dumber and nastier.

  3. Forgive yourself for procrastinating.
    A cool study shows that students who forgive themselves for past sins here procrastinate less and perform better in the future.

  4. Test yourself
    “A powerful finding in laboratory studies of learning is the ‘testing effect’ whereby time spent answering quiz questions (including feedback of correct answers) is more beneficial than the same time spent merely re-studying that same material.”

  5. Pace yourself.
    People remember things better when they do a bit every day rather than cram for exams.

  6. Vivid examples may not always work best.
    some research suggesting that learning abstract concepts rather than the juicy stories that illustrate them enables students to more easily apply the concepts to diverse challenges.

  7. Take naps.
    taking a nap not only makes you more effective,
    also a way to offset some of the negative effects of sleep deprivation when the pressure is on.

  8. Get handouts prior to the lecture
    Students who get handouts in advance take fewer notes, but still tend to better on tests, at least according to one recent study.

  9. Believe in yourself.
    Self-belief affects problem-solving abilities even when the influence of background knowledge is taken into account. The students’ belief in their own ability, called ‘self-efficacy’, and their general ability both made unique contributions to their performance.”

Facing Adversity as a Cow: Guernsey or a Brahman?

Persistence in the face of defeat often makes the difference in outcome.

Ask any farmer, and they will tell you that orphaned Guernsey calves die. It’s not the fact that they die, so much as how it happens, that stays in the mind. An orphaned calf soon gets so hungry she picks a new mother from the herd. The cow promptly kicks the strange calf away. After all, she didn’t give birth to the calf—why should she feed it? The Guernsey calf gives up, lies down, and slowly starves to death.

The orphaned Brahman calf gets a different result. The same scenario plays out, with the calf being kicked out by the reluctant mother. However, in this case, the naturally persistent calf keeps coming, until the potential new mother acquiesces out of exhaustion. As a result of this persistence, the calf survives.

Persistence is hard. It’s hard to get kicked in the face and to keep going. It hits at your self-esteem. You begin to wonder if you have value. You begin to think you might be crazy.

Kirigami – Origami with Cuts

Source: Quanta, Jan 2015

The mismatch between soccer balls, saddles and sheets of paper lies in their “intrinsic” curvature, a property of surfaces known to mathematicians for centuries that no amount of folding can change. Scientists have sought a bridge across the divide — a systematic way of imbuing flat surfaces with curvature, which they say could revolutionize the design and assembly of three-dimensional structures and help extend a major theorem of geometry.

Reporting their work in December in Physical Review Letters, the physicists present a basic set of rules for cutting and reconnecting a piece of paper in order to add curvature to one point in its surface while subtracting it from another, maintaining the paper’s overall flatness while forcing it to bend into the third dimension.

“It’s a way of encoding three-dimensionality in a two-dimensional structure,” said Randall Kamien, a professor of physics at Penn who heads the research group behind the result. “The whole thing will just pop up all by itself.”

The new work essentially provides a rule book for a restricted version of kirigami, a less famous cousin of origami, the ancient Japanese art of paper folding. Origami approximates curved surfaces through folding, which changes paper’s “extrinsic” curvature in space. But through a combination of folds and cuts, kirigami artists produce Escheresque stairways, domed cathedrals and undulating water waves by embedding curvature directly into paper. Kamien and his team have shown that even their restricted kirigami, in which cuts and folds must preserve the spacing of a honeycomb lattice on the paper’s surface, allows the construction of a virtually unlimited range of 3-D structures.

The rule book turns kirigami into a new and efficient approach for designing 3-D structures, researchers said. Whereas building objects with origami requires intricate folding, construction in kirigami is simply a matter of closing the holes that have been pre-cut in paper or any other flat material. “Just by printing holes onto something, you control how you pop it up,” Santangelo said.
