Sorry I really do not know.

i think i have read about big car industry companies (like tessla & wolex) testing their auto-driving cars in roads.they have lunched the test a few years ago and those cars have passed long distances through highways in america without any problem.

interesting and a good-to-know-story!

Do you know of any other famous experiments? What are they?

Current famous experiments are the Elon Musk's Neurolink to integrate an eletronic chip into our brain to boost its creative thinking, data processing and many other capabilities of the brain. It sounds to me like a Johnny Memonic The Keanu Reeves Old Sci-Fi Movie, but I hope this will work harmlessly with our Bio Organ Structured Brain.

Another one so far is the Uber's Driverless Cars experiment and that is now nearly a success without any casualties. Another exiciting news is the Japanese's Flying Car Experiment and it is now successful. But will take some time to bring for our everday use with low cost.


Could you please explain, why the sentence "He never saw the pitch drop" about Professor John Mainstone is true?

Thank you in advance.


Hi Adam,

The text does not say directly that John Mainstone did not see the pitch drop, but that is certainly the implication. We are told that he missed seeing it three times and if he had seen it we would expect this to be mentioned (He finally saw it in...). Furthermore, the question asks 'Which of the following sentences is not true...?'). The singular verb ('is') tells us that we are looking for one sentence, not two, and the third sentence is clearly not true. By a process of elimination, therefore, we can see that the first sentence must be true.

In today's lecture we're going to be talking about experiments.

Is there any different in meaning between these two sentences?

Hello Ola Jamal

There isn't so much a difference of meaning as there is a different perspective on the future event. The first one, which is in the future continuous, uses the continuous aspect, which can express many different ideas. I'd have to know more about the context to say what it means here, but it could express that it's what the speaker expects, for example. The other one expresses more of an intention. The same person might use both of these sentences; which one you use often depends on how you imagine the future event.

Hope this helps.

All the best
