Monthly Talks at London Canal Museum

    Our monthly talks start at 19:30 on the first Thursday of each month except August. Admission is at normal charges and you don't need to book. They end around 21:00.

November 7th

    The Canal Pioneers, by Chris Lewis. James Brindley is recognized as one of the leading early canal engineers. He was also a major player in training others in the art of canal planning and building. Chris Lewis will explain how Brindley made such a positive contribution to the education of that group of early “civil engineers”.

December 5th

    Ice for the Metropolis, by Malcolm Tucker. Well before the arrival of freezers, there was a demand for ice for food preservation and catering, Malcolm will explain the history of importing natural ice and the technology of building ice wells, and how London's ice trade

February 6th

    An Update on the Cotsword Canals, by Liz Payne. The Stroudwater Canal is moving towards reopening. The Thames and Severn Canal will take a little longer. We will have a report on the present state of play.

March 6th

    Eyots and Aits-Thames Islands, by Miranda Vickers. The Thames had many islands. Miranda has undertaken a review of all of them. She will tell us about those of greatest interest.

    When you think of the future,you imagine having some sort of robot friend in your life.Musio,a new robot unveiled recently,is something like that.

    Musio is an artificial intelligence software that runs on Google's Android mobile OS,and is packaged in the form of a round little robot with pointy ears.It doesn't move around,but it has a digital screen for its eyes and heart that are used to express the robot's emotions.It also comes with a remote pointer device,called Sophy,which is used to detect objects that trigger different interactions with Musio.

    The robot was created by AKA,a company specializing in machine learning and natural language processing.It's designed to interact with its users with a voice interface,much like you'd use Siri.But Musio's creators,Wilmington, Delaware-based AKA Study,stress that this is a much different experience than using Siri—Musio can have interactive conversations and remember information about its users,sort of like a little person.Musio can do all sorts of things like controlling home automation and it has a number of integrated sensors.The robot is also programmable and it is able to speak naturally.It is designed to share its emotions via faces on its LCD screen.There are three versions of Musio that vary on hardware.The Simple version has a 1.2GHz dual core processor,1800 mAh battery, 16GB storage and isn't internet connected.It can only recall the last five conversations it has.

    Beyond running on the open source Android platform,Musio is also Arduino compatible.The Arduino platform is an open source electronics platform built to be easy to program.Its purpose is to take different inputs through a suite of sensors and then relay commands to lights,motors,or actuators as a result.Musio is also compatible with the Zigbee wireless standard used by a range of smart home devices,so it's possible that developers could intertwine the robot with other appliances and turn it into a sort of voice-activated smart home hub with a personality.

    And there are several educational accessories that come with Musio,such as flash cards and a fold-out accordion board book.Using Sophy,the pointer,Musio can interact with these objects thanks to a Bluetooth low-energy connection and a special code implanted in the printed materials.

    When I was young I wanted to be a model,so when a national contest was staged,I convinced my parents to have a try.I was selected and told that I was talented and that for only $900 I could attend a weekend event which dozens of the most famous modeling agencies from around the world would attend.At 13,my hopes of fame and fortune clouded all judgment and I begged my parents to let me go.We have never been rich,but they saw my enthusiasm and agreed.

    I imagined being signed by some famous model companies.For months,any boredom or disappointment I faced was pushed aside because I knew I would soon have the chance to be a real model.I thought I would grace the covers of famous magazines!

    Of course,I wasn't signed,but what hurt the most was being told that if I grew to about 1.75metres I could be a success.I prayed for a growth spurt（冲刺）because I could not imagine giving up my dream.I made an appointment with a local modeling agency and the agent demanded $500 for classes,$500 for a photo shoot,and $300 for other expenses.My parents only agreed after hours and hours of my begging.

    The agency sent me out on a few auditions,but with every clay I didn't receive a call,I grew more depressed.The final straw came in July after I had decided to focus on commercial modeling.There was an open call in New York City.We spent hours driving and another few hours waiting,only to be told that I was too short.I was depressed.

    Years later,I realized that the trip to New York was good as it made me notice I didn't actually love modeling, just the idea of it.I wanted to be special and I was innocently determined to reach an impossible goal.The experience has made me stronger and that will help me in the future.

    Birds' feathers are some of the most strikingly variable animal characteristics that can be observed by the eyes. The patterns that we see in birds' feathers are made up of combinations of scales, bars, and spots.

    We already know why birds have colored feathers. Generally, the color of feathers may protect a bird from being noticed by the enemy in the environment, or it can make a bird more appealing to potential mates by helping them to stand out. These aspects are well known. A greater mystery has been how the patterns are created.

    Dr. Ismael Galván and his team studied the color of feathers to see what types of colors were present in birds' complex feather patterns. The study shows they mainly consist of two types of colors: melanin（黑色素）, which produce a range of black, grey, brown, and orange color, and carotenoids（类胡萝卜色素）, which are used to create brighter colors.

    Birds cannot produce carotenoids on their own. For feathers with bright colors, birds must consume food items that contain these paints, and the carotenoids circulate through the blood and to the feather. Melanin, on the other hand, is produced by special cells in the birds' bodies.

    The team found that about 32% if the species studied have complex color patterns, with the vast majority of these complex patterns produced by melanin rather than carotenoids. If the birds were artists, they would use carotenoids as a broad brush to produce color patches, with melanin as a detail paint brush to produce more complex designs.

    But a few birds are exceptions to this rule: Three bird families do have complex patterns without melanin.

    I work with Volunteers for Wildlife, a rescue(救援) and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival(存活) is never certain. However, when it works, it is simply beautiful.

    I got a rescue call from a woman in Mutton town. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2­to-3­week­old owl. It had already been placed in a carrier for safety.

    I examined the chick(雏鸟) and it seemed fine. If I could locate(定位) the nest, I might have been able to put it back, but no luck. My next work was to construct(建造) a nest in a tree.

The homeowner was very helpful. A wire basket was found. I put some pine branches(松树枝) into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

    Now all that was needed were the parents, but they were nowhere to be found. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

    A nervous night to be sure，but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded(回应) to the recordings. I drove over and saw the chick in the nest looking healthy and active. And with it was the greatest sight of all — LUNCH！The parents had done their duty and would probably continue to do so.

    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. While the limits of a person's intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

    It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随机地) from population, it is likely that their degrees of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.

    Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degrees of intelligence.
