Imagine a car travelling at a legal 60 mph on a straight country road and an identical car, also travelling at 60 mph, coming towards it and they collide head-on. The effect on each car will be like driving into a brick wall at 120 mph, their speed relative to the other car.
Now imagine you’re standing beside the road where they collide. If we ignore the small variation caused by the angle between your line of sight and each car’s direction of travel, you will see both cars travelling at 60 mph relative to you.
Now imagine you’re in a helicopter travelling at exactly 40 mph at right-angles to the road and you pass over the place where they crash at exactly the moment they do. As you approach the road, the speed of each car relative to you will change even though their speed and yours remain constant relative to the road.
Now imagine your helicopter is approaching the point of impact at an angle of less than 90o, or approaching in a regular curve round a central point 1 mile from the point of impact. Now calculate the speed at which each car is moving relative to you.
At this point, I have to tell you I failed my A Level maths quite impressively so I don’t even know how to start calculating the relative speeds of the cars and the helicopter but there are two important things to remember: (a) the speed at which anything is travelling can only be measured against an external point, which might help explain Einstein’s idea that nothing can travel faster the light and (b) if you’re driving, it’s not just the speed shown on your speedometer that decides how bad a crash will be.
Another horrifying number that really needs some sort of comparison to give it a context is that, of 2,000 women killed by men from 2009 to 2021, 170 of them were killed by their sons or grandsons, 70% of whom had mental health problems. The research was carried out by Prof Rachel Condry and Dr Caroline Miles, from Oxford and Manchester universities, in collaboration with the Femicide Census, and is to be published shortly so the full report may give a perspective by comparing the figures with the number of men killed by their sons or grandsons in the same period, or equivalent numbers from other countries or different time periods.
It was glad to hear that the film ‘Anora‘ won several Oscars, because I’d seen and enjoyed it – none of the ‘villains’ was actually that villainous, Anora herself was believably naïve and some of the scenes had me laughing out loud. What I didn’t notice was that the F-word is apparently used 479 times, an average of almost 30 times a minute over the 140 minutes of the film, or once every two seconds, which is a new record. Just imagine it: “What do you do for a living?” / “I count the number of F-words in movies.” / “Are they good films?” / “I don’t know, I’m counting the effing effs.”
Mind you, with my hearing as bad as it is, I struggle to understand the ‘normal’ dialogue so I probably missed the swearing.
There was an interesting article this week by Rachael Groessler, a writer who lives in Brisbane who first noticed hearing problems when she found she could no longer eavesdrop on people at neighbouring tables (which was also one of my favourite hobbies). Groessler suffers from a specific and rare form of deafness but I have had similar problems for many years as I’ve gotten older: in crowded rooms and bars where a lot of different conversations are going on, I find it very difficult to separate the voice of the person I’m talking to from the background noise.
Curiously, the consonants go first while the vowels remain, giving rise to some surreal mishearings. When I turned the radio on in the car last week, I landed in the middle of a programme about Roman gods which didn’t make much sense until I realised they were talking about Venus, not a Penis.
When I realised I was going deaf, I did of course get (free) NHS hearing aids. These improved some things but not the full spectrum and the top three keys on the piano still made only a clicking sound and produced no audible note. An added complication of hearing loss is that, if your ears are different, you misjudge the direction a sound is coming from, which is particularly annoying if you’re trying to find the bird with that unusual call.
Then of course, one’s nearest and dearest sees an advertisement and suggests you look at the miraculous hearing aids offered by people who’ve graduated from used-car sales training and are tremendously keen to get their commission. So I went to a private shop and they convinced me their hearing aids would do everything the NHS ones did but much better, and all for only £3,000 because they have a special discount on this week (you know the spiel).
What they failed to mention is that their hearing aids are just one step ahead of the NHS ones and the NHS will catch up quite quickly. I gave them a year or so to improve my life and, after failing to notice any real difference, I had a long fight with Boots to get 50% of my money back. To be fair, you can pay for prettier ones that are less obvious from outside if you care about people seeing them, but I don’t.
Talking of what one hears, I read that Timothée Chalamet spent a long time working with a professional harmonica coach so, when he played Bob Dylan in the film ‘A Complete Unknown’, he could make it sound exactly like someone has accidentally trodden on the cat.
