I get so tired of the kind of hyperbole that opens this article. If an untrained person deliberately dives into 28F water mostly they get cold and quickly get out. How do I know this? Am I a physiologist? No. Am I survival expert? No. I took a trip to Antarctica and the tour operator let passengers dive into the water, swim to a nearby platform and get out. The group of braves souls was about a dozen in number and aged from mid-teens to mid-50's. I even have pictures.

Yes, if you unexpectedly fall into freezing water you can involuntarily inhale and drown. Diving in, swimming a few strokes and climbing out is nowhere near invariably fatal.

All the intrepid divers I saw survived unscathed.

I am an Extra class licensee in the US and while I have a lot of respect for the Ham community, deeply entrenched thinking places the future of amateur radio in jeopardy. If we only allow CW and SSB phone as truly open and accessible operating modes a whole world of technical innovation and integration will be lost. While the letter of the FCC rules might exclude some of the more recent digital modes listed, the traffic is not encrypted. With all the strong encryption out there in the world, it's hard to buy amateur radio as a threat to national security unless we're worried that a bunch of 80 year olds are going to take up arms against the republic.

To me it sounds like some operators have sour grapes because they can't immediately listen to everybody's traffic. In short I support Ham moving forward and not becoming even more antiquated than it is.

I do think the headline of the article is poorly written as I don't think this is about spectrum allocation in any way.

My father worked for Aerojet General in the early 60's. I have clear memories as a child of hearing thunderous booms while the northern California sky was a cloudless deep blue. I remember the sound as loud but by no means intolerable. I do not know how far the flights were occurring from where our house was in Sacramento.

You are right. NYPL is about the best public library one could hope for and much is available from home login. City College is one option to look at but I don't think they have a medical library. I am an NYU alum and had extensive conversations with the alumni office and library and both confirmed that access to med school library resources was a non-starter. I guess its a big issue for me because people need information to make informed healthcare decisions and so much medical research has a component of public funding. Thanks for your thoughtful comment.

Stunningly in NYC there is not a single medical library that offers journal access open to the general public. The only publicly accessible medical library has been described to me as primarily a "historical" library without journal access.

Columbia and NYU's medical libraries are only open to medical school students and faculty. No undergraduates. No alumni. The New York Public Library has surprisingly good online access but is missing a number of important journals and current issues are often delayed by agreement for several months.

If in this nation's largest city, current healthcare knowledge is bulkheaded from public access there is a serious problem. Whatever the publisher's rights these knowledge and information asymmetries must not be allowed to continue.

Motion smoothing TVs have to please two very different viewers. Motion smoothing is great for for sports. Football and basketball, auto racing are good examples. When a pass is thrown downfield and the camera whip pans to follow it, motion smoothing helps the picture stay coherent and prevents ugly artifacts and fans presumably enjoy the game they are watching more.

For movie fans it's a different story. People want a certain filmic softness to motion pictures. Motion smoothing makes a lot of content look like it was shot with very deep focus. The soap opera effect. Early video cameras were not super versatile in terms of depth of field.

I guess my question for the engineers here is this. It there a way to encode a content type code within the signal or the sideband (if that's the right term) that sets could use to automatically optimize their settings. It's not like sports fans ever say, "hey I love those artifacts", or movie buffs "hey, I want it to look like Search for Tomorrow".

I observed a total knee replacement surgery where the surgeons were not using their preferred system due to the fact that the patient already had one knee replacement and the doctors felt the same system should be used on both sides. The representative from the implant company was in the OR for a couple of good reasons. The first was that every system uses different jigs and guides to aid in the resection of the bone and placement of the appliance, the representative helped the doctors understand how to use the system. The second reason was that the surgeons needed to have access to a range of component sizes to make sure they could place a correctly sized implant. Using the same system on both knees also helped ensure that the geometry of both knees would be consistent.

At the time I was pretty stunned that the rep was talking the docs through the operation but the procedure was successful and I learned that when new devices are introduced it is very often the company that trains surgeons in its use.

The practical takeaway here underscores the advice in Auerbach's authoritative text Wilderness Medicine. If a person interacts with potentially rabid animals and that interaction results in even the smallest scratch or contact with saliva the victim should undergo rabies treatment and if possible have the animal undergo necroscopy.

The odds of surviving rabies once it becomes symptomatic are negligible. They can throw the hail Mary from the 5 yard line in a snowstorm but the chances of winning the game with it are slim.

Europe's historically much higher petrol prices have created a long standing culture of smaller cars as well as smaller trucks competing for the same space. Massive Suburban's are among the most common car service vehicles in Manhattan.

But the population of Manhattan is within a stone's throw of Paris overall and the density is significantly greater in Manhattan. Overall population and density matter as the equate to more diverse needs in the population and more users in any transit space.

Population size matters as does density because there are more people that need to fit in a smaller footprint. The original post states that other cities should employ Copenhagen like solutions but the room simply does not exist in NYC no matter how much we would wish it so.

Amenable means open and responsive to suggestion; easily persuaded or controlled. NYC is none of those things. Yes cars take physical space but I think you underestimate the diverse needs and populations that drive the use of cars vs. bikes. Commuters from Westchester county are not going to ride bikes. Frail elderly people and de-conditioned office dwellers are not going to ride bikes.

Comparisons with Northern European cities simply do not make sense however much people would like to force fit them

Apologies, Wikipedia list km2 first for one and mi2 for the other. I still land in the middle though with Manhattan being 6 and change more dense than Copenhagen. I apologize for my haste and error.

Commenting on cycling is always fraught but here are a couple of observations. The population of NYC is 10x that of the city of Copenhagen. The population density of Manhattan is approximately 6x that of Copenhagen (corrected from earlier mistake). Solutions that work in small European cities do not necessarily scale in a manner that would be useful in other international metropolitan cities. Cycling advocates often point to successes in Northern European cities that represent entire different transportation landscapes from other larger cities around the world.
