You can tell how old a tree was by the rings in its trunk, but where do they come from? James May is here to answer.

I'm a big fan of all of James May's work. Having said that, can I point out that palm trees don't have rings not because they are in the tropics but because they are in fact not trees at all but are a form of grass and their "trunk" is made up of the bases of former leaves.

Few people on youtube are interested in grammar. Some perhaps are annoyed that you question Mr May's grammar, because he is so well-spoken. But the answer to your question is that both forms are correct: "more dense" is used here for emphasis.

if it was a 6 yo kid who din't know a thing trying to do this and then had that message, I would agree. But this is obviously high quality so, I don't see anyone being bothered too much by them asking for something that is literally Free, maybe if they are too lazy/value their time more than what its worth. but that's not most people (Its a great channel with loads of content and regularly added content, frankly, its under-rated and deserves more subscribers. they should employ these tactics.

The video is very informative and answered my questions because I live very close to the equator and once worked at the lumberyard. Many large trees that had been cut here either have few rings or none at all which buffled me for years because it's not what I saw on books which contains pictures of trees with rings.

Trees are like pipes that grow larger. Removing water from a tree through the root circulation, is an electrostatic process as well. The electrical current assists the drying of the tree. The constant connection to the air amplifies the soggy electrical char process. The rings become more pronounced with height. Like a stone that is tossed into a pool; the magnetic force rings outwards. The char field ring is the external inner and is most intense. Remaining strongest at the outer edge of the tree pipe; the electrical field grows in harmony with nature. Soggy Charing can produce Sapp as well. Juicing is part of the anticoagulation electrolysis process within the tree. Barks help with iron dye drawn through the root torrents. At the roots, there is photosynthetic pumping drawing water upwards: Also small root branches spew water out as larger roots pull water the opposite way. Dominant suction has leak roots. While those smaller roots are leaking back into the soul; they are part of a larger pull. Extending upwards are connected effective thin currents of water also. Those small roots can cause a substantial differential in the trees inner stir. A tree is a powerful filtration center that works at keeping oils separated; using a complexed electrical process. Weather changes the shape of the water using momentum. The tree follows the shape of its' own water. cJT...aka.. Charlie John Thomas

Because I'm an EFL student who wants to master the English language and normally you don't use "more" with one-syllable adjectives, or do YOU? I have to say I'm quite shocked that most people give me thumbs down, is it really that common to say "more dense" or do people have no interest in English grammar at all?

Yes, seriously! I was just curious because every English teacher would tell you it's wrong to use 'more' with this particular adjective and even my Oxford dictionary has only the form 'denser' in it. So I only wanted to know if there is any particular exception to this rule or if he said 'more dense' just to put more emphasis on it. Nothing more, nothing less.

There is a way. After drilling a core sample the scientist can do their studies, reinsert the sample and the tree will naturally heal itself. A lot can be learned from this for the study of botany. Do some research on the-purpose-of-taking-tree-core-samples.

As for why we 'hear' thoughts in our head, this is most likely due to how we sometimes process information by having a conversation in our head. Language is an audio stimulus. As you read this, your brain is receiving visual stimulus, but encoding it as audio, as that's how you're used to processing this language. A good example is to put a caption next to a picture of Morgan Freeman. As you read the caption, you imagine it being said in Freeman's voice - even though its all visual stimulus.

See what you mean? I was replying to someone else. Not all animals have blood, and if you cut a tree in two, the "top" part won't live long (the bottom will probably end up dying too, if you cut it close to the ground). Also, some plants' sap circulation does sound remarkably like a heartbeat, when recorded and sped up.

The force of Gravity on earth will always attract objects, to accelerate at 9.81ms. Of course the Hammer and Feather have their own gravity, and theoretically the hammer has much more than the feather. But gravity is such a weak force, that the difference in weight between the feather and the hammer is insignificant next to Earth's mass. In an atmosphere the density of the hammer is greater, making it stronger against air resistance than the feather, so they fall at different speeds.

No, hemolymph definitely isn't (and doesn't even resemble) blood, just as feathers aren't fur and chitin isn't skin. It's transparent, flows through body cavities (not through veins), and doesn't carry oxygen (the main function of blood). Anellids, for example, have both hemolymph and blood. And cnidaria (corals, jellyfish, etc.) don't even have hemolymph. Only a small percentage of animal species has blood. BTW, your "definition" of blood ("a fluid resembling blood") seems to be recursive.

Im a little hazy on my Grammar but I think its something to do with the 2 meanings the word dense has. If you were to refer to someone as being dense, ie stupid then the noun for that would be denser. But if your looking at the word in a quantitative sense then it like 'the density increases' then grammatically speaking its 'more dense' However I could be completely wrong and its the TV companies dumbing down.

I never said they had a heart. I said they had circulation, and that it could sound like a heartbeat. And no, if you cut a tree (covered in bark, as opposed to plant) near the bottom of its trunk, it generally won't grow again. And the top part of the tree (now horizontal, lying on the ground) won't "spring back to life". Just because a tree doesn't die instantly when you cut it (just as some animals don't) doesn't mean they're not alive or that they won't die.
@moonpieface7627

sorry, YT changed my name, same person. The top part could easily live on, and keep growing if it gets nutrients again... it could even be years, and still it could spring back to life, so, was it dead and brought back to life, or always alive? And same with the bottom part, leave it and it will grow up again. sap circulation have to do about the time of the day, they are more active in daytime, that still doesn't make it a heartbeat. it's not a heart, and it's not beating.
