Maybe not your infant, but this is certainly not any sort of universal truth. Possibly you could argue that physically attending to the infant themselves is not a full time job, but all of the associated tasks in maintaining any sort of functional environment (food, dishes, laundry, etc. etc.) is, at least to me, at least a 9-5 job.

Our son demanded by wailing or screaming to be held during all waking until at least 12 months, including sleeping for more than 10 minutes alone. I worked from home during this period and I cannot fathom having been at home alone with him and attending any meeting or focusing on a task in a realistically productive way.

I am a groundwater modeler (hydrogeologist) and often work in fractured rock (mainly for mining clients). No experience with modeling for hydrothermal projects though. While the physics of modeling fluid flow in these environments is possible (e.g. discrete fracture networks), mapping and having confidence in the distribution and actual inter-connectivity of the fractures (i.e. preferential flow pathways) is incredibly difficult.

Sure, 90% is an overestimate of the portion of water applied for irrigation that returns as recharge to the groundwater system.

However that number is not zero in the Lower Colorado River basin. I work in groundwater modeling for various clients in the desert southwest, the number we assume for agricultural return flow recharge varies based on crop type and other factors. 90% is an overestimate, 0% is an underestimate

Government debt is not the same as household debt. The government, as the issuer of its own currency, has the power to create money. This ability sets it apart from households, businesses, and city or state governments that rely on income and borrowing to finance their spending.

Government debt is a byproduct of government spending. The primary purpose of government spending is to inject money into the economy, creating demand and stimulating economic activity. When the government spends more than it collects in taxes, it runs a deficit and issues debt as a way to accommodate the excess spending.

Taxes are thus a tool to manage inflation. By reducing the amount of money in circulation, taxes help prevent excessive demand that could lead to inflationary pressures.

Groundwater "age" is typically considered in terms of residence time, that is the period of time between entering the subsurface and exiting at some discharge location. These analyses are often based upon the hydrogeochemistry and the decay rate of known isotopes, hence the mass spectrometer.

Shallow, unconfined aquifers often contain "young" groundwater, on the order of decades or centuries. For example snow melts on a mountain, downhill into a flatter coarse grained area where it enters the groundwater system. The groundwater then moves downdip along the bedrock contour through and into the deeper alluvial basin, eventually naturally discharging into a river or is pumped out at a well.

It would be interesting to read their paper to understand how they (i.e. what isotope) can date back to 1.6 billion years.

Left to their own devices, wild mammals have to cross significant human barriers (roads, neighborhoods, fencing, etc.) to repopulate certain natural areas which they have been exterminated from.

Where I live in Southern Arizona, re-population efforts for bighorn sheep have been successful in the mountain ranges near cities (Tucson). Access to these ranges from nearby "naturally" populated areas (50+ mile distances) requires crossing the interstate, fenced in train tracks, ranches, and extensive urban development. Since their extermination from certain areas, this has not happened naturally (and is arguably not possible). I think similar arguments could be made for the Mexican Wolf population in the southwest.

I agree in principle that ecosystems will re-equilibrate on their own, but given the current state of human development certain areas would remain off-limits for various animals without human intervention, maybe leading to certain species or subspecies becoming extinct. I'm no wildlife biologist but would defer to one on this topic.

TikTok has great content and I am far more entertained and educated there than any other of the engagement-driven "social media" apps (i.e. Meta products).

The problem I find is that it is basically mindless engagement, everything is really too short to get into it, the comments are garbage, and it's extremely entertaining and therefore addictive and a waste of my free time.

I believe Rush did become famous on television, but after the mid-90s it was really all about his radio program. So it might be to your point, fundamentally it isn't the internet, or TV, maybe it was radio.

I do believe that the Rush style radio talk show lays the foundation for Tucker Carlson and all of the conservative pundit TV programming. Which is the basis for the problems we see with Facebook / Fake News etc.

I've had variations on this dream several times. I was talking to my father about it, and he still occasionally dreams about this. As a 67 year old, 5 years retired, 40 years after graduating...

CalTrans actually found out about it after 9 months, inspected it, then left it up for an additional 8 years before the entire sign was replaced.

For about nine months, only a small group of people knew that the Interstate 5 shield hanging above the 110 freeway was a forgery. Then one of Ankrom's friend leaked the story to a local paper. And that's how Caltrans found out.

Ankrom had hoped he could get his sign back from Caltrans after they took it down; he figured he would hang it in an art gallery. But Caltrans didn't take the sign down. His guerrilla sign had passed the Caltrans inspection.

More than eight years after after Ankrom's sign went up, he got call from a friend who noticed some workers taking it down. It had been replaced with as part of routine maintenance.

I'm a big fan of Matt Levine's "Money Stuff" column on Bloomberg - he always has amusing and insightful commentary particularly on Elon -

My Bloomberg Opinion colleague Liam Denning points out that “Musk’s move may also indicate that Teslas weren’t flying off the shelves as a result of accepting Bitcoin payment,” and in fact it’s not entirely clear whether Tesla has sold any cars for Bitcoins.[2] I hope it hasn’t. I hope Musk can make the price of Bitcoin go up or down by 10% by announcing that Tesla will or will not accept Bitcoins for cars, without ever actually accepting any Bitcoins for any cars either way. There’s something pure about that: The price of Bitcoin depends on Elon Musk’s attitude toward it, not on the existence of any grubby commercial transactions in which Bitcoins are exchanged for cars.[3] The source of value for Bitcoin is not its use as a currency or economic importance; the source of value for Bitcoin — for everything — is simple proximity to Elon Musk.

On most mining properties in North America and elsewhere, driving is strictly on the left. This is because haul trucks have such large blind spots to their right side, it's best to give them a clear view of the side of the road (which may be a sheer drop-off).

I've done a fair amount of driving on site, and it's a bit of a trip. Usually right after the main gate there is a cross-over point where you yield and switch sides. And don't forget to drive on the right after you leave for the day!

Pizza Dough 8 years ago

That's a good idea, pre-heating it under the broiler. I do finish the pizzas (last ~2 mins) under the broiler as well.

I have a new oven, so my time estimates are still fairly approximate.

Pizza Dough 8 years ago

I have a baking steel, I preheat the steel at 450 (my maximum oven temperature) for at least 30 minutes. Pizza is baked in ~5-8 minutes.

Real pizza ovens are much hotter.

Self driving haul trucks are already at work at a few open pit mine sites around the world. These are vehicles driving relatively short, prescribed routes, with well defined patterns. The few articles I've read seem to indicate they're operating just fine, although I'd be interested to learn more. If the cost savings are there, I'd bet the entire mining industry will move in that direction rather quickly.
