@primarily_prog A beautiful, perfectly crafted, piece of music. Super strong album, with one of the greatest prog rock songs to finish.

[HalfOpenUmbrella @HOUmbrella]

@primarily_prog Just listened to the first couple of tracks. Lovely stuff. Gotta love a Hammond organ. Thanks for pointing out this one - a new one for me.

@YesterdaysBrit1 Repetition in comforting in comedy. I understand that this wasn’t everyone’s “cup of tea” but it had a marvellous Britishness about it. Could never be made today as stereotypes aren’t funny - apparently.

[HalfOpenUmbrella @HOUmbrella]

@SyndiTypo @ZackPolanski Exactly. I have much more respect for him now compared to many other commentators.

@TheNorskaPaul And I suppose education, languages, English and physiology departments will be advertising for cis or trans men also to address gender imbalance?

[HalfOpenUmbrella @HOUmbrella]

@TheNorskaPaul Just in time for the next good weather hopefully. (Or climate change heat wave as we now call it). Enjoy the staff party and the holidays!

@simonso15792314 @YesterdaysBrit1 @Rainmaker1973 Muted - the cowardly quiet sound of someone who can’t admit they are wrong!

[HalfOpenUmbrella @HOUmbrella]

@simonso15792314 @YesterdaysBrit1 @Rainmaker1973 Ok. I don’t want to get into a pedantic argument, but seeing as you are being argumentative, let me tell you that you are simply wrong. The Mach “term” is not what you think, it is a ratio of the speed of an object to the speed of sound in that medium. Undefined for a vacuum.

[HalfOpenUmbrella @HOUmbrella]

@simonso15792314 @YesterdaysBrit1 @Rainmaker1973 I don’t wish to be patronising, but I appreciate it will come across that way. You need to understand what a Mach number represents. The Mach 2 for Concorde was (correctly) based on the speed of sound at the altitude it flew at. There is no Mach number for a vacuum.

[HalfOpenUmbrella @HOUmbrella]

@simonso15792314 @YesterdaysBrit1 @Rainmaker1973 It’s not Mach 4.4, but it is 3400mph.

@elbow112 @PaulPitt1967 Shocked and saddened. Loved his lyrics in the morning. Never met him, but felt like I knew him. Thoughts with family.

[HalfOpenUmbrella @HOUmbrella]

@TheNorskaPaul Is there an admission by the Treasury that numeracy levels are different amongst demographic groups? That sounds a little racist to me.

@WG_RumblePants Closure announced today.

[HalfOpenUmbrella @HOUmbrella]

@TheNorskaPaul @TulipSiddiq Let me think……

[HalfOpenUmbrella @HOUmbrella]

@KateLee86 @Steven41849941 Just for info and without comment. 1994 (30ish years ago).

[HalfOpenUmbrella @HOUmbrella]

@atlbell929 @theepicmap And the same for cars, with the same restrictions.

@VWolf83864177 @MathMath901 But the answer to the question is A or B - not all of them as you have said. Your value of vi in the equation is the vertical velocity. A and B have a larger vi so therefore a larger vf.

[HalfOpenUmbrella @HOUmbrella]

@Marion202501 @Math_files She’s not a maths girl if the she thinks too has 2 letters.

[HalfOpenUmbrella @HOUmbrella]

@VWolf83864177 @MathMath901 That assumes an initial vertical velocity of zero, unfortunately.
