This week I’m sharing a quote, a tweet, and a library.
Quote I’m Pondering
“The faintest ink is more powerful than the strongest memory.“
Human memory is fallible, where written notes do not forget. The quote encourages note taking, but implementing that lesson is not trivial. As the exercise of observing a candle can demonstrate, a common occurrence can give rise to tens of distinct observations. Time is finite, and so is the detail in which notes can be taken. I tend to take comprehensive notes inconsistently, which suggests that I attempt an unsustainable level of detail. Ultimately the value of memory or note taking to a situation that has not yet occurred is unknown.
Problems in Science
Science can seem apolitical from the outside, it is often perceived as a rational and collaborative exercise in furthering understanding of the natural world. In reality humans, their endeavours, and the systems they build to achieve them, are all flawed. The incentives of academic research prioritise production of highly cited research papers, creating races to publish ideas first, which ultimately stifles collaboration and sharing. This tweet shares the story of an observation stolen by a visiting professor. The subsequent conversation between scientists in the thread reveals a nasty and paranoid reality of scientific research.
This week I celebrated both two years with ONI and twenty seven years of life in general. I felt particularly cared for by the people around me, and appreciated both that this is the case, and that I am aware and able to enjoy the feeling. It is one thing to accept someone into a community, but it is even more difficult to make them feel accepted.
Things I wrote this week:
Training Fasted, a spontaneous experiment I conducted, noting how my physical performance shifted in response to not eating over a 30 hour period.
I played two games of Captain Sonar, a chaotic submarine-warfare themed board game between two teams who must work cooperatively to out maneuver their opponents. Not an easy game to learn, but a lot of fun.
Short version: A few big things to talk about; nuclear war, bribes, engineered environments, mistakes, and courses.
In Oxford I enjoy meeting people passionate about studies I might not have otherwise ever considered. This week I was introduced to ALLFED, a group who spend their time working out how to feed the population who survive a nuclear war. In the current political climate it can be both frightening and paralysing to think the fate of billions rests on the whim of a few individuals. Knowing some out there are trying to be prepared give me confidence that humanity can survive its own incredible destructive power. This work fits under the umbrella of Effective Altruism, which is persuasive (I have a few friends who are strong proponents) but also complex.
There is a common understanding that bribery is wrong, but it is not immediately obvious why. The answer I seem to find is that the central issue of bribery is when a person is able to take an advantage for themselves (the bribe) in exchange for acting against the external interests they represent (e.g. the university in the case of a college admissions administrator). Some examples:
This year a scandal broke regarding admissions to US colleges, where coaches were bribed to select students without athletic ability on an athletic basis. At face value the harm here appears to be a violation of meritocratic principles; students ought be selected on their talent rather than the wealth of their parents. In fact generally wealthy parents are able to have their students attend top universities despite their academic or sporting ability, via large donations to universities. The wrong here comes from the coaches personally profiting from the student’s admission, rather than the university itself.
People have managed to make some incredible changes to their environment. This week The Wave opened in England, an artificial lake that generates artificial waves so that people can surf. There is also warm weather skiing on plastic and the more extreme indoor ski slope cooled to negative temperatures in hot Dubai. The football world cup will required air conditioned stadiums. All this gives hope that technology can repair the damage we are doing from burning fossil fuels, but also these feats of engineering require enormous amounts of energy themselves.
Depending on your familiarity with logarithms, this may either appear indecipherable or trivial. I particularly remember encountering logs around the age of 15, and it being the point in my mathematical learning where maths stopped being intuitive. It was confronting to not find the subject easy. Unfortunately I couldn’t see or be shown how pushing past that initial discomfort would lead to valuable personal growth, and I moved away from mathematics to subjects I “felt I was better at”. I think the feeling of being overwhelmed, of being stuck, drives many people away from opportunities to grow and empower themselves, and it is a feeling I am still striving to become more comfortable with.
Short version: I ate an apple, which got me thinking about climate change. I’ve also been talking about mental health. Purdue went bust. Not every article with 300 citations is novel.
Climate Economics: Food Miles
I was eating an apple, here in Oxford, and discovered from the oft mocked apple sticker that it had been grown in an orchard in New Zealand (on the other side of the planet). This struck me as a problem; surely the fuel in transporting food around the world is an externality contributing to climate change. I wanted to know the specific quantity of fuel burned to make this possible, and found this study from New Zealand university Lincoln that claims there is a smaller climate impact from consuming New Zealand apples in the UK compared with local ones. I am sceptical, and will hope to follow up on this in a later post, but the data is summarised in table 7.3 on page 72. Summarising and converting the units to equivalent millilitres of Diesel burned we get:
Equivalent Fuel Burned (diesel in mL) per apple (assume 100 g) for:
Direct energy consumption at orchard
“Chemicals” e.g. fertiliser pesticides
Shipping (NZ) and “Cold storage” (UK)
So New Zealand is much more efficient at producing apples (about 5x less energy per apple is needed at the orchard), which largely corresponds to better yield per area of land (at 50 tonnes vs 14 tonnes of produce per hectare in New Zealand and the UK respectively), but also is due to better use of renewable electricity generation in NZ (particularly hydroelectric, wiki links to UK and NZ). This energy difference is almost entirely closed by the fuel used in shipping, but the use of “cold storage” of apples in the UK emits a further 44.8 mL equivalent diesel burned.
In short, the study suggests that fresh apples in the UK cause the same emissions per apple as New Zealand apples shipped to the UK, but if the apples are kept in refrigerated storage then the UK apples have a worse impact on the climate.
One notable thing from this exercise is that when you buy a 20p apple at Tesco, you are also paying for about 15p of diesel that was burned to get it from the tree to you.
This week’s Economist cover is a graphic that describes the warming climate. Meanwhile this photo article from the Guardian (also this week) hit me emotionally. The climate is changing, and the effects are disturbing. Currently my approach is very ivory tower: observing and considering, but not actively campaigning. I have friends who are much more active in Green Political Parties and movements like Extinction Rebellion. I think it may be time to explore similar options. I could blog each week about climate change in an attempt to raise awareness, but I would be very surprised if any of my readers were unaware of the issues?
Last week my friend Jessy shared some insight from her time answering a crisis hotline (read on facebook or linkedin). At work we now have staff trained in mental health first aid. It is good to see mental health issues lose their stigma, even if it is a gradual process. I thought someone might find things I do to maintain good mental health useful.
Mental Health Tool kit (or “Things I do that I think help me mentally”) Have a plan: Be enrolled in a health care program, have a GP, speak to them about mental health. Know services in your area. Have hotlines in your contact list. (If you broke your leg or developed an odd growth you would know what to do, what if you broke your mind or developed an odd pattern of thoughts?) Reflect: Write things down to get them out of your head. Write a couple words about how you feel each day somewhere. Notice if something keeps coming back. Even just putting information somewhere else helps me relax that I won’t forget it, so I can let it go even briefly. Exercise: Match the mental stress with physical stress, release endorphins. “Get out of your mind by getting into your body”. Do something that makes you sweat for 10 minutes. Endorphins make you feel better. Matching the physical stress to your mental stress helps align how you feel. If you are physically worn out, you will sleep. Sleep: Get good sleep. Put distractions far away. Passing out from alcohol is not sleep. Eat Clean: Sugary oily foods (fast foods) taste great but make you feel terrible. You also know that they are bad for you so you feel guilty. Eating well makes you feel better. Control: Organise your room. Go somewhere you want to (ideally under your own power like walking or cycling). You have so much freedom and power. Remind yourself of this by using it. Breathe: Slow your breathing. Count four on the way in, hold for four, count four on the way out, hold for four, repeat until you don’t remember how long you’ve been trying this. Mindfulness: Take some time to practice mindfulness (this is a skill that I can’t explain in a couple sentences, but I’d recommend trying the free sessions on Headspace). Unplug: Go offline. You don’t need technology to survive. Switch off. Leave smart devices behind. Even leave your watch behind to lose track of time. Just be.
On Monday Purdue Pharma filed for bankruptcy. Opiates are incredibly useful and powerful drugs, but are also addictive. The US over prescribed them, peaking at 81.2 prescriptions per 100 persons in 2010-2012. Those prescriptions and subsequent addictions and addiction related deaths are linked to the marketing of OxyContin in many lawsuits against Purdue Pharma. For a humorous take on a dire situation, see John Oliver (April 2019).
Quirks of Academia
A high school student in Australia recently published in a mathematics journal, and it made the news. I have read some slightly bitter comments along the lines of “so what”. There is a lot of pressure inside academia to publish papers (a metric of performance) and seeing a relatively simple result gain media coverage can inspire envy.
