n1(kn4m3!We miss youThis is a great podcast. Well written, researched, produced, and recorded. Informative. Interesting. Funny. Everyone saying you should come back is right! I am a young scientist who wants to be a chemist when she grows up, and I’ve enjoyed this show a lot. Much love and thank you for your work so far, a random kid from Iowa

SnuffalupacephalopodAmazing!This podcast is incredible. So well done. It is pure gold (or pure ‘valuable element of the listener’s choice’).
-
AmandafrancisSo interesting!!I really wish I could give this podcast 6 or 7 stars instead of just 5. Very well produced, super interesting, and often funny. I love it!
-
KJGChemistryInteresting, Exciting, and PoeticThis podcast is absolutely amazing. I am a high school chemistry teacher and just started listening to this podcast on my commute. It has been so fun! I have learned so much. I am always learning fun things that I can relate to my lessons. I have to say one of my favorite aspects of this podcast is the poetic nature of the speaker. The speaker is very eloquent and just has a way with words. I do have to ask though — when is the next episode?! Can’t wait to hear about uranium! Thanks for the podcast!
-
Wilsonac2Awesome learning experienceSo fun listening to stories that teach valuable lessons in both chemistry and history. Please make more.
-
oLiVErSaPPleiDAmazingI can’t believe that it’s such a good series. T.R Appleton has skillfully made such a catchy series that (for me) kept me entertained (and learning) while traveling. This is the best podcast I’ve ever played in my life.
-
Broken heart ranchFantastic to start with 💕It just gets better and better! Thx
-
neon,tetraThis is absolutely awesomeThis show is amazing I’ve never know so much about this stuff. I can’t wait for more episodes

J D'AmoreGreat for science nerds and beginners alikeMy partner and I love this podcast. She has a chemistry degree, whereas I have always struggled understanding science, and we both get so much out of the podcast. For her, it is an opportunity to learn more about the history of what she understood on a technical level, and to refresh her memory about things she hasn’t studied in a while. For me, it inspires me to learn more and provides a great foundation to build on, whereas other introductory material tends to be less interesting and harder to absorb. Many scientists, technicians, and engineers I know complain that STEM schools don’t care much about teaching the humanities, history, social consciousness, and critical thinking. Because of that, I particularly appreciated TR’s insistence on highlighting ethical and political concerns that come up in the history of chemistry. Many episodes explore the chemistry industry’s disturbing (and not just historical but ongoing) role in imperialism, capitalism, ecological destruction, and the military industrial complex. This critical approach, alongside TR’s infectious passion for the hard science itself, challenges the audience to consider how to use science for the good instead of for violence and profit, which is depressingly all too common. This is vital achievement in science communication. TR finds stories about each element that can be fascinating, bizarre, informative, inspiring, and silly (bad puns abound!) The result is a fantastic balance of education and entertainment. I wish more podcasts were like this!
-
gamingboy1956Amazing podcast!T. R. Appleton is clearly a gifted podcaster and makes detailed episodes about each element. Please keep this going till the last element. This gives me such more info than Wikipedia and it’s fun listening to. Please keep this going!!!
-
Starchief58Great PodcastThis is without a doubt my favorite podcast! I have looked for a book about the discovery/history of the elements for years and came across this podcast. It’s been super informative! Thanks!!!😀
-
SophiellinAmazingI have caught up with all the episodes. Each element is wonderful on its own, but you take that to another level. Can’t wait for Protactinium!
-
Dingo6.8.12Great Science Podcast. Period.I’m a science teacher and this podcast is exactly what I hope my class can be: educational and entertaining. The stories TR tells highlight the genius of scientists of the past and the connections of chemistry to our daily lives. I can’t recommend this highly enough.
-
mrpeters714Amazing!This is a fantastic podcast. We just finished ruthenium. My sons favorite has been strontium.
-
brock medleySo Great!Each episode of The Episodic Table of Elements is like being chem lab partners with American Shadows, The Memory Palace, Backstory, and Criminal. With the dulcet tones of T.R. Appleton being comparable to Phoebe Reads a Mystery. When I get to the end, I go right back to hydrogen and start again. Thank you T.R.!
-
willyboi15In depth and entertaining- GREAT SHOW!Please keep this going forever, Love the show
-
ev-the-lynLOVE this podcast!!I used to listen to this on my commute (not so much now lol) but I listen whenever and it’s great! The host (T R Appleton) is clearly a gifted podcaster and the episodes are clear and engaging. He should do more podcasts!
-
Unapologetic_NerdFavorite Science PodcastThis is truly my favorite of all of the science podcasts I listen to! Mr. Appleton provides a delightful array of anecdotes each episode which I often find myself sharing with others even if I can’t get them to listen to the podcast themselves. I have been working my way from episode 0 onward for a little while now and have thoroughly enjoyed each and every one. I look forward to each episode I listen to and hope that this podcast only ends at the end of the periodic table, if then! Keep up the fantastic work!! :)
-
binhytSo much funSuch interesting and lovely podcast.
-
LeyniaLOutstanding podcast: Episodic Table of the ElementsPodcaster TR Appleton blends a wealth of information to present in an enriching, entertaining way. He not only informs, but can spark interest and exploration to those who are eager. Such are the differences, imo, between information and education. Listeners to The Episodic Table are the beneficiaries of Appleton's knowledge and skill--at no cost! My college courses in chemistry, on the other hand, were expensive, and they did not strive to stimulate or make relevant.
-
htcakesEndlessly fascinatingSuch a fantastic podcast! A skillful blend of sly humor, art, literature, history, and technology that teaches and entertains. Bravo!
-
PwdrskirThe Chemistry I Never UnderstoodNot being particularly good at the subject in school, I have acquired a new found fascination for Chemistry from listening to this podcast. Truly interesting stories diving into the history of each chemical. Well done.
-
dogchasetailForced chem student.Currently in school taking pre req classes. Halfway through 7 chem classes.😬. Really nice to have a narrative enjoyable chem talk to listen to. I love hearing the history. Can’t wait to hear through the entire periodic table!😄
-
SouthofCheeseGreat Podcast!This is my first podcast review. I’m on episode 11 and like this so much, I’m inspired to give this positive feedback. The subject has been covered before but Mr. T. R. Appleton does a great job keeping it interesting, humorous, and fresh. The website for the podcast is also a great companion piece. How can this have no commercials in it?!? Where is this guy’s sponsors? I feel like I should start a small business just so I can pay him for a commercial spot. I am hoping to hear something in future episodes, just so I see this getting the support it deserves!
-
KingIkemayLoving this podcastSo happy I happened to watch SciTech the day you were on. I knew I was going to like it before the interview was over. Nice mix of stories. I also like the part about how to collect each element.
-
TLerryThank you for the smart interesting podcast!Thank you kind redditor who recommended this!
-
Cowboys#1fsnReally fun and informativeLove it!
-
abcd12345Wonderful!I found this while looking for science test prep material for an upcoming Jeopardy! audition. I was pleasantly surprised by how captivating each episode has been- a great mix of both science and history! Will continue listening even after my cramming obligations are over!
-
FSZARGreat show!Thanks for doing this podcast!
-
stinkeye_smilesBetter than it ought to beComing from a person that has had little to no interest in chemistry up to this point, I love this podcast that was recommended to me by a friend. This is a smart and fascinating look at the elements that comprise everything in the Universe. The stories behind their discoveries and how they fit into our lives are very well told. Looking forward to more and anxious to find out more about the less common elements at the bottom of the table.
