A small corner for my favorite quotes, vocabulary words, and books.

“You should never be in the company of anyone with whom you would not want to die.”

- Frank Herbert, God Emperor of Dune

“Human knowledge is never contained in one person. It grows from the relationships we create between each other and the world, and still it is never complete.”

- Paul Kalanithi, When Breath Becomes Air

“Man does not simply exist but always decides what his existence will be, what he will become the next moment. By the same token, every human being has the freedom to change at any instant.”

- Viktor E. Frankl, Man’s Search for Meaning

“Although we know the end of the maze holds death (and it is something I have not always known—not long ago the adolescent in me thought death could happen only to other people), I see now that the path I choose through that maze makes me what I am. I am not only a thing, but also a way of being—one of many ways—and knowing the paths I have followed and the ones left to take will help me understand what I am becoming.”

- Daniel Keyes, Flowers for Algernon

“We all come into existence as a single cell, smaller than a speck of dust. Much smaller. Divide. Multiply. Add and subtract. Matter changes hands, atoms flow in and out, molecules pivot, proteins stitch together, mitochondria send out their oxidative dictates; we begin as a microscopic electrical swarm. The lungs the brain the heart. Forty weeks later, six trillion cells get crushed in the vise of our mother’s birth canal and we howl. Then the world starts in on us.”

- Anthony Doerr, All the Light We Cannot See

“J’aurais dû être plus gentille—I should have been more kind. That is something a person will never regret. You will never say to yourself when you are old, Ah, I wish I was not good to that person. You will never think that.”

- Khaled Hosseini, And the Mountains Echoed

“But at times I wondered if I had not come a long way only to find that what I really sought was something I had left behind.”

- Jon Krakauer, Into Thin Air

“I am composed of the formal and the material; and neither of them will perish into non-existence, as neither of them came into existence out of non-existence. Every part of me then will be reduced by change into some part of the universe, and that again will change into another part of the universe, and so on forever. And by consequence of such a change I too exist, and those who begot me, and so on forever in the other direction.”

- (Translated by) George Long, Meditations of Marcus Aurelius

“Maybe nothing ever happens once and is finished. Maybe happen is never once but like ripples maybe on water after the pebble sinks, the ripples moving on, spreading, the pool attached by a narrow umbilical water-cord to the next pool which the first pool feeds, has fed, did feed, let this second pool contain a different temperature of water, a different molecularity of having seen, felt, remembered, reflect in a different tone the infinite unchanging sky, it doesn’t matter: that pebble’s watery echo whose fall it did not even see moves across its surface too at the original ripple-space, to the old ineradicable rhythm.”

- William Faulkner, Absalom, Absalom!

Proverbs + Aphorisms

  • Audentes fortuna iuvat — Fortune favors the bold (Attributed to many including Pliny the Elder and Virgil)
  • Festina lente — Make haste slowly (Caesar Augustus)
  • Cogito, ergo sum — I think, therefore I am (René Descartes)
  • 七転び八起き (Nanakorobi yaoki) — Fall seven times, rise eight
  • Was mich nicht umbringt, macht mich stärker — What doesn’t kill me makes me stronger (Friedrich Nietzsche)
Word Definition Example
Scrambling Climbing steep, rocky terrain using both hands and feet with limited technical gear. Grade 1-3 with 3 eliciting internal ruminations on why you are doing this in the first place. The final stretch to the summit required careful scrambling.
Glissade Sliding down a snow-covered slope, typically in a controlled squatting or seated position. We saved hours on the descent by glissading down the snowfield.
Dead Time A purposeful timing delay inserted between switching events of two semiconductor devices to prevent simultaneous conduction. Improper dead time on the GaN HEMTs led to shoot-through during high-frequency (MHz) testing.
Parasitics Unintended impedances (resistance, inductance, or capacitance) inherent in real circuits. Parasitic inductance in the layout caused unexpected voltage spikes at high frequencies and the parasistic resistance increased conduction loss.
Ringing Oscillatory voltage or current behavior caused by parasitic elements or Si diode reverse recovery during a switching transient. The Flyback converter MOSFET voltage waveform showed significant ringing after turn-on. In this case, caused by resonance between the MOSFET Miller and junction capacitances and the parasitic loop inductance
Snubber A circuit used to suppress voltage or current transients in switching systems. Adding a snubber reduced the overshoot across the device in the Forward converter.
Soft Switching A technique where a voltage or current falls to 0 before its counterpart rises resulting in a non-existant or small overlap loss. Generally, ZVS turn-on is preferred for MOSFETs and ZCS turn-off for minority-devices like BJTs. That Half-wave (HW)- ZVS Quasi-Resonant (QR) buck switch cell problem on the exam only achieved soft switching when the normalized inductor current is greater than 1.
Reflow A soldering process where old solder or paste is melted to improve electrical connections. After reflow, the microcontroller began sending I2C signals again.
Cold Joint A poorly formed solder connection that results in weak electrical contact. The intermittent fault was traced back to a cold joint on the connector.
Yoke The control column used to pitch and roll the aircraft. Gentle inputs on the yoke kept the aircraft stable on final approach.
Stall A condition where an aircraft wing exceeds its critical angle of attack, regardless of altitude or engine power. The instructor pulled the yoke until the horn buzzing intensified and the aircraft dropped after entering a stall.
Aileron A control surface used to manage roll about the longitudinal axis. A slight aileron input corrected the bank angle during the turn.
Squawk A four-digit transponder code used to identify an aircraft on radar. Common codes include: 1200 (default in U.S. for VFR when not communicating with ATC), 7500 (hijacking), 7600 (radio communication failure), and 7700 (general emergency). ATC instructed us to squawk a new code after entering controlled airspace in Broomfield.
Assembly A low-level programming language. Also group of people gathered together. We had an assembly to discuss migrating the assembly code from LC-3 to the new x86 interface.
Bedazzled Greatly impressed or awed. She was bedazzled by the new stepper motor that ran at 1 MW without cooling.
Bodge To make or repair something clumsily or hastily. He managed to bodge the PCB connector with some luck and a lot of flux.
Brownout A drop in voltage in a power supply, not a full blackout. We experienced a brownout during testing.
Delineate To describe or portray precisely. The author delineated the process clearly.
Heisenbug A bug that changes when you try to observe it. Tracking that Heisenbug was a nightmare.
Memoization Storing results of computations for reuse. Memoization reduced runtime significantly.
Pandemonium Wild disorder or chaos. The lab was in total pandemonium.
Quixotic Exceedingly idealistic; impractical. His quixotic goal never ended.
Rat's Nest A tangled mess of wires; most commonly known as airwires when first starting a PCB layout from the designed schematic. The rat's nest gave the engineer a myocardial infarction.
