A couple of weeks ago when e-bikes were banned from TfL services, we mused on what TfL's announcement might be. • All types of e-bike, e-scooter and e-unicycle are banned except foldable e-bikes. We now have TfL's wording which you can see on this poster. Big letters: No e-scooters, e-unicycles or non-foldable e-bikes Smaller letters: allowed on TfL services.* Small letters: Failure to comply may result in prosecution. Tiny letters: * E-bikes are permitted on the Silvertown Tunnel cycle shuttle service and on the Woolwich Ferry "No e-scooters, e-unicycles or non-foldable e-bikes" is probably the optimum wording. In terms of importance e-bikes should be at the beginning, but the use of "non-foldable" would then be ambiguous so it's best at the end. Non-foldable is a much better word than unfolded which I'm glad has been summarily dumped. That was the poster. "Non-foldable e-bikes are prohibited on TfL services except for the Silvertown Tunnel cycle shuttle and the Woolwich Ferry." This starts well and then gets bogged down in exceptions. Over half of the announcement is about where e-bikes aren't banned - two services used by maybe a few hundred cyclists weekly so of minimal relevance. Alas over a loudspeaker you have to say the asterisk out loud and this gives it undue prominence, lest some e-bike warrior be fooled into thinking they can't cross the Thames downstream of Tower Bridge. The announcement's also a triple negative with "non-foldable", "prohibited" and "except for" to try to get your head around. "Customer information. All folded and unfolded e-scooters and e-unicycles are prohibited on TfL services. Non-foldable e-bikes are also prohibited on TfL services except for the Silvertown Tunnel cycle shuttle and the Woolwich Ferry. For more information speak to a member of staff. Thank you." The "no e-bikes" message is utterly buried here because someone's felt the need to incorporate e-scooters and e-unicycles too. I don't know about you but I hardly ever see e-unicyclists around London, let alone sneaking onto the tube with their single wheel steeds. Sure they're banned but no way do we need to be reminded about this every five minutes, it's total overkill. What we've got here is a brand new no e-bikes policy the public needs to be told about, but dressed up in faff so that the campaign makes far less impact than it might. This is what happens when you plump for precision over simplicity. And all because words are difficult, however they unfold.

A lion’s mane jellyfish can release up to 45,000 eggs per day. The jellyfish’s strategy is to lay as many eggs as possible and leave them to fend for themselves. Most of these eggs don’t survive, probably fewer than 0.1%. In ecology, this approach is known as a high reproduction selection—better known as r–selection. Fish, […] The post The jellyfish knows how to survive uncertain times appeared first on Herbert Lui.

You remember a fragment of a song that sounds like it’s from the eighties. You do some research, but you struggle to remember where you heard it, and when. Your guesses are more imagination than recall. No hints come to mind.  When this happened to Questlove, he was stumped. He decided to transform this research […] The post From research to imagination appeared first on Herbert Lui.
