The internet and airwaves are full of advertisements offering to make you, your home, your car and your workplace smell better. It all seems innocuous because our sense of smell is always turned on, and we seem to be fine as we breath in scents from household cleaners, body soap, shampoo, cologne, scented candles and air fresheners. But that perception is belied by invisible dangers from these products. The headline for a piece summarizing a recent study regarding particulate pollution from indoor scented products says it all: "Scented products cause indoor air pollution on par with car exhaus ..read more

There's no telling exactly where the Trump administration's trade war is going as the president authorizes tariffs and then quickly suspends them, only to authorize them again and suspend them again or provide waivers for certain industries. While tariffs on narrowly defined categories of goods to guard against unfair competition may be workable, the administration's shotgun approach to tariffs risks a cutoff of strategic minerals that could strangle America's tech industry. As I've written before, the United States is dangerously dependent on other countries for a wide-ranging list of metals ..read more

There is a so-called U. S. government "efficiency" drive currently underway delegated by President Donald Trump to unelected billionaire Elon Musk. Whether Musk has the authority to do what he is doing has become a matter for federal courts (for example, see here and here). In this piece I want to discuss the underlying assumption behind Musk's approach and see if it makes sense, namely, whether the government should be run like a business. Spoiler alert: It shouldn't be and can't be. That's because there are important overarching differences between the goals of government and those of a busi ..read more

The ongoing takeover of U. S. government computer network by a small cadre of radical technologists—with the blessing of the current president of the United States—demonstrates just how vulnerable democratic norms and organizations are to determined technologists who understand the central role of computers and the information stored on them in any modern organization. With the federal IT infrastructure now increasingly under the control of this group—under what is now being revealed as the false banner of efficiency—the entire population of the United States has become exposed to various form ..read more

Before cutting the ranks of U. S. government employees who safeguard the nation's nuclear material and respond to nuclear accidents, it would seem wise to ask them exactly what tasks they are assigned and how they accomplish them. Apparently, that was not a consideration when the Trump administration through its U. S. Department of Government Efficiency Service (currently run by billionaire Elon Musk) began firing personnel at the National Nuclear Security Agency (NNSA). What is happening at the NNSA is a window into why merely downsizing an organization does not necessarily increase its effic ..read more

Whether or not you share the zeal for cuts in government spending embraced by President Donald Trump and his billionaire sidekick Elon Musk, you should know that giving Musk and his callow team of computer coders access to payment systems at the U. S. Department of Treasury risks a global financial meltdown. It doesn't make such an event certain, but it lowers the odds considerably. Here's why: First, the U.S. Department of Treasury processes some $6 trillion in payments each year. If that system were to come to a halt for even a relatively short period of time, the consequences would be devas ..read more

In 1865 British economist William Stanley Jevons explained to the public that increased efficiencies in the use of resources per unit of production do not generally lead to lower consumption of those resources. Rather, these efficiencies lead to higher consumption as many more people can now afford the more efficiently produced goods which carry a lower price tag. Jevons was referring to coal, the cost of which was falling and demand for which was rising due to increased efficiencies in production. His idea became known as The Jevons Paradox. When the Chinese-based artificial intelligence (AI ..read more

While the world was focused on the actions of the Trump administration in its first week, a little-known Chinese startup startled the tech world last week with the release of an open source artificial intelligence tool that for a fraction of cost and resources of American competitors such as ChatGPT matches and in some cases outperforms its American rivals. The company, DeepSeek, has gone even further, making its eponymous tool available for download for free. Only those seeking to use the company's application programming interface―something which allows the tool to interface more easily with ..read more

The sensible Swedes like planning ahead. This time its storage for nuclear waste from its own nuclear industry—storage that is supposed to last 100,000 years. Nuclear power currently provides 40 percent of Sweden's electricity from six operating reactors. The Swedes expect to fill the storage site—"60 km of tunnels buried 500 metres down in 1.9 billion year old bedrock"—sometime by 2080 at which time it will be closed. For understanding whether the target of 100,000 years of successful storage is plausible, I suggest a trip back 100,000 years to understand what surprises might be in store over ..read more

I recently noticed that the elevator at my favorite cinema has been out of order for weeks now. The less mobile patrons need that elevator to transport them downward to this underground theater. I then learned of America's "elevator crisis" and my mind wandered to the struggle to maintain the Roman Empire. I'll explain the connection below. But first a refresher on Rome's predicament: The Roman emperor Trajan brought the Roman Empire to its greatest extent during his reign (98 to 117 A.D.) with his successful conquests in what we today would call the Middle East. Rome's many conquests had been ..read more
