Humble Pi
What makes a bridge wobble when it's not meant to? Billions of dollars mysteriously vanish into thin air? A building rock when its resonant frequency matches a gym class leaping to Snap's 1990 hit I've Got The Power? The answer is maths. Or, to be precise, what happens when maths goes wrong in the real world.
As Matt Parker shows us, our modern lives are built on maths: computer programmes, finance, engineering. And most of the time this maths works quietly behind the scenes, until ... it doesn't. Exploring and explaining a litany of glitches, near-misses and mishaps involving the internet, big data, elections, street signs, lotteries, the Roman empire and a hapless Olympic shooting team, Matt Parker shows us the bizarre ways maths trips us up, and what this reveals about its essential place in our world.Mathematics doesn't have good 'people skills', but we would all be better off, he argues, if we saw it as a practical ally. This book shows how, by making maths our friend, we can learn from its pitfalls. It also contains puzzles, challenges, geometric socks, jokes about binary code and three deliberate mistakes. Getting it wrong has never been more fun.SPECIFICATIONS:

Flaky and Fickle
Style: Data Transfer (10Gbps)
Worked great for a month. Went to plug in a spare ssd to back up files from tablet and it never has worked since. No data or power through any ports. The light turns on and stays solid but is just dead. Waste of my money for now it is outside of return and I am having troubles getting in touch with Satechi.

Love this thing
Style: Data Transfer (10Gbps), Style: Data Transfer (10Gbps)
I’m really impressed with my Satechi power passthrough 4 port USB C Hub.
It’s really slick, streamlined, and really good looking too.
It works well, doesn’t get hot or even warm to the touch.

Works, but man it is SLOW
TL/DR review follows: This thing does what it claims to do (gives you 4 USB ports that you wouldn't have otherwise), but the data transfer speed of any SSD I connect through this Satechi Hub is half what it is when the SSD is connected via my OWC Hub (data transfer rate is double when connected via the OWC Hub vs. being connected via the Satechi Hub). I'll keep this Satechi gadget (in a drawer) for times when I really, really need more USB C ports and therefore will be more willing to tolerate the data transfer speed slowdown penalty. I cannot possibly consider this to be a primary data transfer pathway however.
These above results are from an M1 Mac Mini with 16GB RAM and MacOS Monterey with speed measured by Blackmagic Disk Speed Test utility.
I did not get similar results on my 11th Gen Intel Core i9-11900 processor PC running Windows 11. Data transfer rates are the same (SLOW) when any USB drive is connected directly to the PC USB C port or when connected via the Satechi Hub. Highly worth mentioning, though, is that all data transfer speeds on the PC are HALF the speed obtained on the Mac Mini when connected via my OWC Hub. All PC data transfer rates were measured by CrystalDiskMark utility
One interesting anomaly worth mentioning is that the PC will not eject USB drives if they are connected directly to the single USB C port on the PC BUT it WILL eject any/all USB drives if they are connected via the Satechi Hub. This particular PC has never been able to eject USB devices correctly. The Mac Mini ejects all these same USB devices correctly no matter how they are connected. All USB drives are formatted Windows NTFS whether connected to the Mac Mini or the Windows PC (for those who care)
Conclusion: An interesting experiment, but for me the Satechi Hub is not worth what I paid for it. I can easily see it being a worthwhile investment for many, assuming undemanding use cases, however

Fantastic, stylish, and easy shoes!
Size: 2.5 Little Kid, Color: Aqua/Multi
My daughter LOVES these and wears them daily. She says they're really comfy and they slip on easily. They've held up for several months of daily wear so far and are still going strong!
