Was it the computer on the Red Dwarf?

[silentC]

Hmmm, seeing as it's nearly knock off time, I'll give you that one. QUEEG 500 was the "back up computer". In fact he was created by Holly, the real Red Dwarf computer, as a prank on the crew. "We're talking April, May, June and July Fools".

Lister had highly illegal learning pills. From whom and where did he get them?

[bitingmidge]

Shane Warne's mum gave them to him, so he thought they'd be ok.

I'm inclined to give you that one - he almost certainly did indeed get them from Shanes mum

Who was Brian's father in the Life of Brian?

It wasn't Mr Cohen either - it was Naughtius Maximus - "then, he, after having his way with me - voom - like a rat out of an aquaduct".

Q. In order to maintain air speed velocity, how many times does a swallow need to beat it's wings every second ?

[Tonz]

Nortius Maximus, a centurion in the Roman army.

Q. In order to maintain air speed velocity, how many times does a swallow need to beat it's wings every second ?

Approx 18 times a second with an amplitude of 18 cm...

Would you be referring to an African or European swallow?

In order to maintain airspeed velocity, a swallow needs to beat its wings forty-three times every second, right?Actually, wrong. By comparing the European Swallow with bird species of similar body mass, we can estimate that the swallow beats its wings 18 times a second with an amplitude of 18 cm:

Species Body mass Frequency Amplitude
Zebra Finch 13 g 27 Hz 11 cm
European Swallow 20 g ≈ 18 Hz? ≈ 18 cm?
Downy Woodpecker 27 g 14 Hz 29 cm
Budgerigar 34 g 14 Hz 15 cm

Note that even the tiny Zebra Finch flaps its wings no more than 27 times a second while cruising.

If we ignore body mass and look only at bird species with a similar wingspan, we can estimate an average frequency of 14 beats per second and an amplitude of 23 cm:

Species Wingspan Frequency Amplitude
Budgerigar 27 cm 14 Hz 15 cm
European Swallow ≈ 28–30 cm ≈ 14 Hz? ≈ 23 cm?
Downy Woodpecker 31 cm 14 Hz 29 cm
European Starling 35 cm 14 Hz 26 cm

By averaging all 6 values, we can estimate that an average European Swallow flies at cruising speed with a frequency of roughly 15 beats per second, and an amplitude of roughly 22 cm.

You were right - then all of a sudden you pull all those figures out your bottom. Although deviating from the original question in actual fact the maximum speed european sparrows can maintain is around 13–14 meters per second, and although the Lund study from Sweeden does not discuss cruising flight in particular, the most efficient flapping of 7 beats per second was observed at an airspeed in the range of 8–11 meters per second, with an amplitude of 90–100° - equating to 17–19 cm. Thus in pushing 43 beats you would be talking of another type of swallow, not euopean. If you were talking about one of the 40 odd species of African swallows them it would of course be a different story.


You were right before you started to get all technical (Plagiarised from unnamed sources.)

"cut and paste" has a lot to answer for...

So whose turn is it :confused:
