Sir ji , please make practical video on cubic system just like you made on tetragonal system by showing tetragonal model of prism and pyramid , please sir
Thank you Sandy for your feedback. It is awesome. Such tricks are given in at glance comparison of all systems w.r.t. cry axes, elements of symmetry ,forms and indices. you watch you will enjoy it. Dr sajid Hundekar Pc Geo Kimberlite
Very simple, crystal clear and easy to understand explanation. Your presentation is just awesome. I am preparing for IIt jam geoloy, I believe this kind of explanation of concepts will definitely help me a lot in my preperation. Thanks a lot for your efforts and dedication towards Geology in making us understand the beauty of Geology. May almighty bless you and shower all of his bounties on you and your family.
Jazakallah khaire Syed Tahir. Thanks for your compliments and appreciation. I glad to know that It will help you in your GATE preparation.I am delighted. You can watch crystallography and structural Geology it will definately add important points in your subject knowledge. Thanks for your feedback.This will be my favourite feedback. Dr. Sajid Hundekar.
Syed Tahir, Assalamoalaikum Rb Wm, I hope you and your family will be safe and taking all precautions during this pandemic. you can watch my videos on Paleontology, Micro-palaeontology and Stratigraphy it will definitely help in your GATE preparation. Crystallography watch all videos you will learn lot of shot cut to learn and love to watch them. A comparison of all seven systems with reference to Crystallographic axes, Elements of symmetry, forms and indices.
Thank you very much for your compliments Sandy. Watch other videos on crystallography and at a glance comparison between all seven systems with reference to cry system, elements of symmetry, forms and indices. short tricks are shared to remember the elements of symmetry forms with indices. I hope you will like it.
Study with Adarsh Thanks. It is good demand but lot of ideas are in my mind. First I would like to prepare videos on basic syllabus of Geology so that those who watch videos they can clear their basic concept which will require for any exam.I will be happy if my content can like by Jam Aspirants. Now my next target will be palaeontology, mineralogy and petrology where students having a phobia. I am in future going to prepare videos on Indian stratigraphy,Economic Geology, Environmental Geology,Disaster Management,Geotectonics.Engineering Geology and General Geology. These videos will definately help the JAM Aspirants. At this moment I am not in the position to prepare JAm preparation or paper solving videos. Thanks for your suggestion in future i will definately work on it.
Please sir help me to clear does axis passes through the centre of faces of the crystal or the edges of the crystal. If they pass through the centre of the face then 100 is ok if this passes through edges then indices will change
In cubic system Galena Type first model cube- in which all three axes are passing through the centre it may be your a axis denoted a1 passing through front and back face pair where as b axis denoted as a2 pass through centre of the side faces pair and c axis denoted as a3 passes through centre of the top and bottom face pair while remaining axis are parallel hence indices will be 100 , 010 and 001. In case if the axis passing through centre of the edges example model no 111 octagedron it consist of 8 similar triangular faces cutting all the edges at equal in length hence indices we will write for only front face 111 but in it depending upon the possition of the face whether it will be located front top side or front bottom side 11 bar1 and if the faces are situated in side left top 111,left bottom 12 bar1,and on right hand side top 1bar11,while on left bottom 1 bar1 bar1 will be the indices. But for mode 1 11 octahedron we normaly wright indices of front face indice 111 Same practice we will follow for all crystal models of all systems. I hope you get your answer and understand the point you raise in your question.
Yes Sandy Now due to lock down nothing can be done but once it will be open I am having a plan to do all types of cubic.and Hexagonal systems to be recorded along with Twin crystal models. viewers asked me to do Monoclinic and Triclinic system also. In pune lock down now extended by another 15 days. Thanks sandy for demanding pyrite type. I like your attitude. Dr Sajid Hundekar Pc geo Kimberlite
sir in rutley's book it is given by class and in bangar it is given by type. Though Im finding type way easier to understand. so basically first comes the system then class and then type and forms? is it?
Ritisha it is one and the same. It is depend upon How are going to feed in your memory ones it is done then you can write as per your choice. No one cut your marks if you not written like Rutley's book. First try to understand in a simpler way.once you know then you can adopt your own style to represent and convience the others. Good observation.keep it up.
@@ritishasingh6867 be practical then your learning make you perfect. Good observation and try your own short cut to memorise in a shortest time. Play with crystal models to understand them.
@@pcgeokimberlite2947 Yes sir I have found some mini boxes similar to tetragonal orthorhombic and a dice and a hexagonal pencil to understand the concept by my own :D One more thing I wanted to ask sir, in the syllabus of JAM under the minerology unit the syllabus is "symmetry and forms in common crystal classes" so for this I dont need to focus (just for now) on other classes apart from normal or common class? I mean the syllabus is saying common crystal classes so that means the class which have most number of symmetries right? Like in the tetragonal system the common or normal class is Ditetragonal Dipyramidal (4/m2/m2/m) which is also known as zircon type. So I have to focus on symmetry and forms of only this class right and not of others?
@@ritishasingh6867 Yaah Good once you understand the 7 system then in the end of it you can try to remember the another name.I had uploaded all systems and at a glance comparision is also done which will be help you in Jam examination.
nice
geo is beautiful
nature is great
Thank you
Sir ji , please make practical video on cubic system just like you made on tetragonal system by showing tetragonal model of prism and pyramid , please sir
Thanks
I already made a video of Cubic system with models
Kindly watch video list
Watch all Crystallography videos .
The trick of multiple of 12 is 🤘fantastic.
