Vinay Gupta on Meditation

What enlightenment is Welcoming the cat We’re not going to actively catch the cat. It is not going to be caught. It is eventually going to come and sit on your lap because you show up in the same place at the same time every day and wait for it. That is a comfortable lap, I will come and sit on it. Emptying the sink The sink is now empty of dishes - how wonderful. It is still a sink. Yes, you are still an ape - you’re just an ape with an empty sink. Is an empty sink better than a full sink? They are both sinks. Yes, but I think you’ll find the empty one is better. But it’s still a sink.

Do I Need to Own a Car? And the Future of Mobility.

I love cars - always have. I’ve been driving tractors as long as I remember. I got my driving licence within three months of when I was legally able to. And this love has expanded into motorbikes, when I first left the rain of the UK and experienced the joys of the Australian mountain roads. Currently I own a car (Fiesta ST) and motorbike (Yamaha Fazer) However, soon I move back to London. I’m incredibly excited for the move - it’s been years since I lived in the city. But with it comes a complication, though - what to do about my wheels?

Your Head is a Houseboat - Campbell Walker

Wonderful book, 5/5. And short - you could read it in an evening. Of course the journalling will take longer - “Cleaning isn’t a one-time act, and neither is exploring and unravelling your head.” Before: At the end of a hard day, you probably feel more exhausted than a fly who doesn’t quite understand the mechanics of a window. You know the fly. They can’t see the open crack in the window and, much to your vicarious frustration, they keep flying at the window pane over and over again. They deplete their energy while going nowhere. On a day where you feel like your head lost the battle, and all the stuff going in won, the fly becomes very relatable.

The Fourth Turning - the High is coming!

Introduction “History doesn’t repeat itself, but it often rhymes.” Time goes through cycles. There is the economic cycle, one which everyone is all too aware of. There are Milankovitch cycles, when the climate changes due to variances in the eccentricity, axial tilt, and precession of the planet (which is separate to man-made climate change). There is Saṃsāra, the Buddhist concept of eternal life, death, and rebirth. Strauss and Howe’s Fourth Turning Model, written in the late 1990s, proposes a generational cycle that can be used to help explain the rises and falls of human history. According to this theory, we’re currently in the Crisis (who’d have thought?)

Imagining the Future of Energy

The harnessing of energy is one of the most transformative shifts in human history. Controlling fire enabled the cooking of food, which potentially led to an increased brain size; coal and the steam engine powered the industrial revolution, initiating accessible intercontinental travel and the spread of culture; and oil turned multi-week voyages into multi-hour trips - and our first steps off the Earth. Energy has been instrumental in human civilisation - and will continue to be so into our future.

Wind and Solar Potential

Which countries have the most potential for wind and solar power? PV Potential Based on data from https://globalsolaratlas.info/., here is a map of the best countries for solar: Unsurprisingly we have the deserts in Africa, the Middle East, and Chile. The map on the source website has much more precise intra-country data, so it is definitely worth checking out. Wind Potential Based on data from https://globalwindatlas.info/, here is a map of the best countries for wind:

Is it MECE? Use a Venn

MECE is one of the most well-known acronyms in consulting. Standing for Mutually Exclusive, Collectively Exhaustive, it is a principle used when doing any form of segmentation, to ensure no duplication (ME) or missed items (CE). This exists in a bunch of scenarios, such as solving problems, writing documents, and preparing presentations. There are countless articles explaining what it is, so I won’t go into too much detail. These often include a Venn diagram or two to show ME and CE, but I haven’t seen them used to demonstrate the whole MECE concept - so that’s what I thought I’d do. Using examples, we can see how a Venn diagram can be used to check your segmentation is MECE.

Fallacies, Politics, and ChatGPT

I thought I’d have a play with ChatGPT, to see if it could help me write about, and refresh my knowledge of, logical fallacies. I also wanted to test some of the various “bugs” I’ve been reading about (for example, it’s terrible with numbers). I asked it for a list of common logical fallacies, then asked it to provide definitions and real examples from political debates. The answers are copy-pasted from ChatGPT with minimal editing. My thoughts on the entire process are further down.

GMAT Quant Notes

I’m not planning on taking the GMAT any time soon, but was curious to see what would be involved anyway. These notes are far from exhaustive - they’re just a few things that I want to remind myself of. Book: GMAT All the Quant by Manhattan Prep. Data sufficiency A. Statement (1) does allow you to answer the question, but statement (2) does not. B. Statement (2) does allow you to answer the question, but statement (1) does not.
