What are the implications of this?
“Carbrain” refers to a person who believes that driving and personal transportation as synonymous and thinks accordingly when deciding to support or oppose transportation infrastructure and urban planning projects.
Other people have described the health effects, so I’ll describe the chemistry. Fats are made of long chains of carbon atoms surrounded by hydrogen atoms attached to a “head”, which is made of other elements or structures. Carbon atoms normally can make a total of 4 bonds. Hydrogen atoms can make 1 bond.
Carbon being able to make 4 bonds means that in the chain of carbon and hydrogen atoms in fat molecules, each carbon atom makes a bond with the carbon atom before it in the chain, a bond with the carbon atom after it in the chain, and then bonds with two hydrogen atoms separately off to the side. This makes a total of 4 bonds. If all of the carbon atoms in the chain are like this, that’s “saturated fat”, because the chain of carbon is completely “saturated” with hydrogen atoms.
(Hydrogen atoms are white, carbon atoms are black, oxygen atoms are red)
Saturated fats have the often desirable property of being able to be tightly packed together, and thus are typically solid at room temperature. Butterfat is mostly saturated fat.
However, carbon atoms can also make a double bond with other carbon atoms. If a particular carbon atom in the chain makes a double bond with the carbon atom before it, it could cause a bend in the chain of carbon atoms. In that case, it also means that those particular carbon atoms in the chain that have formed a double bond with each other only have 1 available bond left (after also forming a separate single bond with the carbon atom before or after it), so it can only bond with one hydrogen atom. These are, therefore, called “unsaturated fats”, and because they don’t back together easily, they are typically liquid at room temperature.
If there is a single double bond in the chain, it’s a monounsaturated fat.
If there are two or more double bonds, it’s a polyunsaturated fat.
Notice how the hydrogen atoms connected to the double-bonded carbon atoms in unsaturated fats can be connected to either the same side or the opposite sides of the two hydrogen atoms. If they’re on the same side, they are called cis-unsaturated fats. If they’re on opposite sides, they are trans-unsaturated fats, or trans fats in short.
This is oleic acid, a cis monounsaturated fat commonly found in many vegetable oils:
While this is vaccenic acid, a trans-monounsaturated fat. It is found naturally in butter and human milk and is not particularly bad for you:
Note that this is NOT the same picture as the one I showed for saturated fat. The 7th and 8th carbon atoms from the left are double-bonded and, therefore, are each missing a hydrogen atom. The one remaining hydrogen atom on each is bonded on opposite sides.
Note that trans-unsaturated fats are also pretty straight. This means that they can also pack together with saturated fats to make a solid product at room temperature.
“Hydrogenation” is the process of adding hydrogen to unsaturated fats to saturate them. This means that liquid oil can be processed into a solid product. That’s how margarine and shortening are made. In previous years, partially hydrogenated oils that weren’t fully hydrogenated could leave substantial quantities of trans-unsaturated fats left in the product, but after health concerns, many countries’ food safety authorities banned these artificial trans fats. Fully hydrogenated fats consist of only saturated fats since they have been “fully” hydrogenated, and that is what food manufacturers have been doing instead.
The point seems kinda moot outside of cities.
Are you expecting a bus stop outside every farmhouse? Who’s going to ride it, cows?
Or in a small town where everything is reachable on foot within fifteen minutes anyway and the road has like 2 cars per minute? Regional bus service that takes you to nearby towns that comes a few times a day is probably as good as it gets.
I don’t know what it’s like in other places but I tend to find that in cities with an actual dedicated serious transportation agency, busses run every hour at minimum. Even regional busses in the small city where I attended university ran 6-8 times a day per line for three very similar routes. Local busses ran every 20-40 minutes depending on time of day. That’s shocking good for a city of 50,000 in America.
A 2025 Toyota Camry is 4.84 m in length. A typical US school bus is 10.5 m in length. The school bus is 2.18 times as long as the car.
You don’t need to convince anyone. People will convince themselves if they are given the appropriate environment. This is about convincing them to support the construction of that environment.
Think about New York. It’s subject to the same cultural influences as the rest of the US but public transportation use remains high because the infrastructure is good and competitive with driving.
I thought I was commenting on a different post. Sorry about that
I hope you realise that the comment you replied to is really just a reference to the Succulent Chinese Meal video.
Opposition to the zipper merge might be a regional thing. Where I’m from, people can zipper merge just fine, especially after the state transportation agency put up a bunch of billboards telling people to do it.
The solution to that is to… not tell them that you want to take their car away. Because if you are a rational urbanist, you don’t.
The source is this article.
It’s not just “technically difficult” to eavesdrop. Properly implemented, it’s computationally impossible to eavesdrop on a connection secured with TLS.
Also, if the car park is smaller due to fewer people driving, it means it will be easier to remember where you parked your car, and you won’t have to walk as far to the destination. It also means you can fit more stuff in the same space, so you won’t have to drive as far to get to the places you want to go, saving you time and fuel!
These arguments are won and lost on the phrasing.
Most people I have found care relatively little about the topic. They drive and think in terms of driving only because that is the context they have been exposed to their entire lives, and there’s not really their fault.
If someone really is that deep into the rabbit hole then nothing you say will change their mind, so don’t waste your time.
Not being end-to-end encrypted is meaningless to law enforcement if Telegram refuses to turn over the chat contents (which they do). Law enforcement can’t just eavesdrop on the conversation without Telegram’s cooperation. The chat contents are still secured by TLS from the user’s device to the Telegram servers.
Smart professional criminals rarely use Telegram for this stuff anyway. There’s WhatsApp and plenty of other popular platforms of end-to-end encrypted
What is the charge? For operating a messaging platform? A succulent private messaging platform?
I really had to run a fact check on this but it really does seem to be true.
Brains are 0.5% plastic by weight and with an average human brain mass of 1.3 kg, that means humans, on average, have 6.5 g of plastic in their brain
For what it’s worth, English Wikipedia editors reached a consensus to deprecate (ban) it for unrealiability last year: https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources/Noticeboard/Archive_424#RFC:_The_Cradle
The following notes are present:
The Cradle is an online magazine focusing on West Asia/Middle East-related topics. It was deprecated in the 2024 RfC due to a history of publishing conspiracy theories and wide referencing of other deprecated sources while doing so. Editors consider The Cradle to have a poor reputation for fact-checking.
Probably. I didn’t consider that, but everything is AI generated nowadays
