Why bumblebee fly

When its thorax is warm enough, these muscles are re-engaged allowing the wings to move and off it flies. Babbity was a Buff-tailed bumblebee queen Bombus terrestris , one of twenty-five species found here in the UK. Humble or bumble, their numbers are in sharp decline, a compelling reason to ensure your garden planting scheme is designed to attract pollinators and to carry out emergency resuscitation if you find one grounded.

Grounded bumblebees found later in the year are another story. The tell-tale sign of ragged edges around the wings show that it is time for it to die and there is little to be achieved in attempting to revive it.

If the wings are intact, then it is likely to be a male who was so busy going about his business that he had become dehydrated. A reviving drink of a sugar and water solution should soon send him on his way again. What struck me about my Babbity Bumble was how small its wings were in relation to its body size and it made me wonder how they ever get off the ground in the first place.

Even when they are in flight, they seem barely in control, forever changing direction and darting hither and thither, a characteristic Rimsky-Korsakov evoked musically in the orchestral interlude to the opera The Tale of Tsar Sultan , which we know as the Flight of the Bumblebee.

The ability of the bumblebee to fly has intrigued entomologists and engineers for decades. Antoine Magnan nailed his colours firmly to the mast in when he wrote in Le vol des insectes that not only bumblebees but all insects should not be able to fly because in doing so they break all the physical laws of aerodynamics.

Aeroplanes work on the same principle, although jet engines rather than flapping wings provide the force required to take off. It took a combination of robotic modelling and slow-motion videos of airborne honeybees for Michael Dickinson and his colleagues at Caltech in Pasadena to understand the curious aerodynamics of bee flight.

Filming at 6, frames a second, they discovered that the wings sweep back in a ninety-degree arc and then flip over as they return, flapping at a rate of up to times every second. In other words, the wings moved backwards and forwards rather than up and down, the speed of the movement coupled with the angle of the wings creating something akin to a mini hurricane around the bee. As the air pressure of these vortices is lower than that of the surrounding air, it is sufficient to keep the bee aloft.

For the curious of mind, the explanation raises further questions, not least how the bee is able to move its wings so quickly. Even the same bee on a different day will pick a new way to flap its wings. The work was partly supported by grants from the National Science Foundation.

I really wish that it would have been socially appropriate to share this with her. Thank you for taking the time to write it! FACT: Scientists do not know everything, and that is a good thing.

Keeps us learning and scientists employed. The real message of the story or myth is that there is a danger in over applying any thought, theory, or philosophy. Many people make science into a religion rather than a discipline. The story of bumblebees illustrated that the law of aerodynamics was and perhaps still is incomplete. People are warned against over applying this story in the same way we must be warned about over applying science.

Science has demonstrated value and many who know this tend not to recognize the demonstrated valued in questioning science. It is in questioning and challenging that science is moved forward.

Those who defend science too strongly perform a dis-service to science and validate the nut jobs who deny science. There is a healthy balance, a middle ground, that recognizes the value of things understood and not understood. Proven science is true until it is dis-proven. This has happens many times in post and modern science. No, the story illustrates that people believe whatever they like and seldom do any fact-checking. So for decades people have discussed how bumblebees fly, the origin of the universe.

Some things we are not meant to understand. I love when I hear that something considered fact by Science is disproved. Tell me how to get my left sock out of the dryer when it disappears or how to get the last bit of peanut butter out of the jar. That would be important and helpful. What, incidentally, is the smallest particle?

Speaking to the gullible nature of humanity.. The laws of physics have been revised to correct errors in the past so if indeed there was a legitimate error that made it so insect flying was a violation of the laws of physics.. Science has proven many times that what it once claimed to be proven true was never proven, or true. It builds models of nature and reality based on our current best evidence.

So it is always rational and justified to accept scientific findings. New discoveries complement the old and usually widen the scope of their validity. This phrase is always used by people who are critical against science that has a personal agenda behind it all, and they do not only expose their ignorance while being at it.

I believe very much in the truth of science. Bees mindlessly hovering not flying is too lengthy and complicated a topic to explain in an already very long blog. You see, worker bees are the most important bees in the colony, but they are sterile and cant reproduce at all. Evolution should predict that mutation should be passed along to the next generation of workers, but as you know, only the queen bee has the babies. Only hundreds if not thousands of scientific research is in circulation to explain this not-so-minor issue.

So is the rest of nature. Every cell of it. Apparently we humans are gifted with our strong convictions and we stick to them. Either God has chosen this to be our nature, or natural selection has found this to be crucial for our species. Maybe we did need it. But the numbers are turning away from it, Jim. And my daughters! Forget it. They are perfectly wonderful, utterly moral creatures, full of compassion, and no god needed. I teach critical thought and take wisdom wherever I find it.

I find value and joy in compassion. No sublime Intelligence needed. Humans are not turning away from it, they are using the same stupidity to cling into new forms of dogma.

Workers are unfertilized eggs. Mutations are passed down from the breeding bees, which generate the workers. Mutations that originate in the workers are not passed down. Fundamentally, it relies on you accepting a short answer that gets you to stop thinking about the question. The flying bumble bee would break the laws of physics if the wings did not do their job of allowing flight……not so fast there, no laws of physics would ever be broken even if it flight was assisted via levitation, since it could be using laws that was not known to science today!

It is a case of the scientists concerned thinking they were smarter than they really are and not applying any critical thinking.
