engineering fundamentals

I… I passed…

So this thought, that as quickly became my headcanon, hit me like a wrecking ball. Lillian hates Lena so much is because she looks so much like her mother. Sure Lillian can just hate Lena because illegitimate but she really can't stand her because she's just reminded of that wrenched woman (who I dubbed Nuala) who was in bed with her husband. And in her mind she's getting back at her by mentally and emotionally abusing her daughter.

*cue dramatic and sad music to go with this headcanon* 

No matter what Lena did it was never good enough to gain recognition from Lillian. To be the first 2nd grader to win first place in the school science fair for her work on energy power devices wasn’t good enough. It wasn’t good enough when she was eligible to skip ahead grades to match her intelligence. She wasn’t good enough when she taught Lex the basics of chemistry engineering and the fundamentals of electronic force fields. When she was offered a full ride to MIT at the age of thirteen, Lillian was completely uninterested even if it meant beating Lex to college. If anything it drove Lillian even further away. 

There wasn’t a single thing that she could do to prove herself and maybe it was always going to be that way. 

It is important to view knowledge as sort of a semantic tree - make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details. Otherwise there is nothing for them to hang on to.

An example of Lenz's Law

An example of Lenz’s Law

Video’s like these; apart from being extremely satisfying to watch, are a perfect representation of one of the most fundamental laws to almost all motors and machinery, Lenz’s Law.

Lenz’s law states that: “An induced electromotive force (emf) always gives rise to a current whose magnetic field opposes the original change in magnetic flux”.

Confusing on the surface, but remembering that:

Brain to robot: 'Move, please'

Using the power of thought to control a robot that helps to move a paralysed hand: a project from the ETH Rehabilitation Engineering Laboratory could fundamentally change the therapy and daily lives of stroke patients.

One in six people will suffer a stroke in their lifetime. In Switzerland alone, stroke affects 16,000 people every year. Two thirds of those affected suffer from paralysis of the arm. Intensive training can – depending on the extent of damage to the brain – help patients regain a certain degree of control over their arms and hands. This may take the form of classic physio- and occupational therapy, or it may also involve robots.

Roger Gassert, Professor of Rehabilitation Engineering at ETH Zurich, has developed a number of robotic devices that train hand functions and sees this as a good way to support patient therapy. However, both physio- and robot-assisted therapy are usually limited to one or two training sessions a day; and for patients, travelling to and from therapy can also be time consuming.
