    I can’t see it as anything but white and gold. However, other photos clearly show it is black and blue.

    Interestingly, if I’m scrolling past, my brain will sometimes perceive it as black and blue for a fraction of a second. I can normally flip optical illusions at will. This one jams me in the wrong viewing mode.

    It’s also worth noting that it wasn’t the hydrogen that caused the fire. The Hindenburg had an aluminium skin. It began having degradation issues, so they painted it. The paint was iron oxide based. Aluminium and iron oxide are the 2 main ingredients in thermite.

    Analysis of the video shows that it was the skin burning off. It would have gone up almost as badly, even if filled with helium.

    I remember when my first was born. 2 different parts of my brain had opposing thoughts.

    1 part was thinking “This is the cutest, most beautiful thing ever. I must protect and nurture them at all costs.”

    The other part was thinking “My god newborn babies are ugly!”

    I can easily see cognitive dissonance pushes most people to the first thought. It’s you being hacked by hormones, an effect that is disturbingly powerful.

    I was also caught out by how much my (male) hormones were affected, even pre birth. It both disturbed and amused my wife.

    I’m a parent. I would also struggle to keep a straight face. My minion might even get a compliment for the insult. They will still be in trouble for it though!

    Parenthood isn’t about being perfect, but just ahead of your chaotic lovable minion.

    I used both options. It’s worth mentioning that, depending where you live, using a drying rack indoors can cause major mold issues. The humidity needs to go somewhere.

    It’s also worth noting that modern dryers are massively more efficient than the older ones. Many older dryers (at least in the UK) could run at around 2.5-3kW. my new one is down to 500W. That energy also gets dumped into the living area as heat, so isn’t wasted in the winter.

    Basically, the equations are not as simple as they first appear.






  • This is one of the biggest frustrations with nuclear power. The first power plants had issues (mostly due to them being bomb factory designs). We learnt from that, and designed better ones. They never got built. They were swamped in red tape and delays until they died.

    Decades later, China comes in and just asks nicely. The designs work fine. China now leads the way, built on research we left to rot.

    It’s also worth noting that there is a big difference between a fusion power plant and a fission one. China is doing active research on it, as is the west. There’s quite a friendly rivalry going on. We have also basically cracked fusion now. We just need to scale it up. The only big problem left is the tokamakite issue. The neutron radiation put off by the reaction transmutes the walls. Using radioactive materials as a buffer is an idea I’ve not heard of. I’m curious about the end products. A big selling point of fusion is the lack of long term waste. Putting a fission reaction in there too might lose that benefit.

    The problem is there are 2 categories. Microwave safe just means it won’t explode, or throw sparks. The other type sorely lacks a name still. It’s the stuff that is transparent to microwaves and so won’t heat up at all, except for heat transfer from the food.





  • The same way your mortgage is backed up by your house. If you default on your mortgage, the bank can take your house in foreclosure.

    Rather than sell shares to raise the money, Musk has backed his borrowing with Tesla shares. Basically, if he doesn’t pay back the loan, the banks get the shares. Unlike houses, shares can change value quite quickly. If the value of the loan exceeds the value of the shares, then the banks start to get VERY nervous. They will call in the loans to get what they can, before things get worse. This could crash the share price further, since they will want to offload the shares as soon as possible.

    Musk is extremely rich. However, like most extremely rick people, his money is tied up in shares. If Tesla falls fast enough, he could end up owing more than he has in assets. As soon as his creditors pull the plug, he becomes bankrupt.

    5g is a lot more capable and flexible compared to older generations. The main one is a massive increase in capacity, for the same frequency allocations. Compounding with this is that it can be directional. This allows several phones to use the exact same channel simultaneously, so long as they are positioned at different angles to the tower.

    5g also uses more frequency bands, allowing even more data to be moved around. Unfortunately, 2g has most of the lower frequencies, higher frequencies carry more data, but have less penetration into buildings.

    Finally, 5g allows for priority and context awareness. E.g. the police can have their phones prioritised, or VoIP calls given priority over video streaming. It can also trade bandwidth for range. This allows a tower to either reach further to cover a larger area, or focus down, to provide more bandwidth locally.

    In theory 5g could have a similar range to 2g. However, that rarely happens. It requires it using the lower frequencies, that 2g currently uses, and well as dropping its data rate to improve range. Most of the time it’s optimised for shorter range, and more towers using higher frequencies. This gives impression of a far smaller range. But give a huge increase is available bandwidth.
