## What is Molecules by Theodore Gray?

INCLUDED IN BEST OF 2014

“Few iOS apps are as thoughtfully designed as Molecules, and even fewer combine superb visuals with clear writing that encourages exploration.”
– Macworld

“Molecules uses its predecessor as a springboard to further greatness.”
– Stuff

A book about molecules, and a chance to touch, stretch and twist them!

Molecules by Theodore Gray is the extraordinary sequel to The Elements, the bestselling book and app. It continues the story of the elements to show how they are assembled into the rich diversity of compounds, chemicals, molecules, rocks, and stuff that make up our world.

The app includes an important world first: a touch-interactive molecular dynamics simulation that lets you poke and prod hundreds of different molecules, seeing how each one reacts to your touch. Molecules are not static things – they twist, turn, vibrate, and spin in an elaborate and beautiful dance of quantum mechanics.

The app incorporates the NAMD simulation engine developed by the Theoretical and Computational Biophysics Group at the University of Illinois. These are serious, scientifically accurate simulations. A few minutes playing with them will give you a deeper intuition about the true nature of molecules than years of study on paper. And while they are serious science, they are also a whole lot of fun to play with!

In addition to the amazing wiggling molecules, the app contains the entire book of Molecules, with all the objects interactively rotatable so you can see them from all sides. Going further than The Elements, the app includes dozens of innovative and intriguing “still life videos” that reveal the true nature of substances through close-up interactive video.

Features include:

• Try out the first ever touchscreen-interactive molecular dynamics
• Bend, squeeze and shape 348 different molecules using multiple fingers
• Increase or decrease the temperature and see how molecules react
• Read the full text of all 14 chapters of Molecules by Theodore Gray
• Understand the movements of molecules in a special chapter for the app
• See over 500 videos and rotations of incredible objects photographed by Nick Mann

### 4/5 — Molecules by Theodor Gray

*2026-01-14, version 2.0.1*

Sono ben 4 anni (troppi) che questa bellissima applicazione non viene aggiornata! Tra l’altro sembra che qui nessuno legga le recensioni perché vi è già stato scritto che manca il supporto alla lingua italiana. Le altre due applicazioni di questo autore hanno il supporto alla lingua italiana; quindi non si capisce come mai questa applicazione non supporta anche la lingua italiana. Pertanto confidiamo in un solerte e sostanzioso aggiornamento per fornire il supporto alla lingua italiana. Grazie mille e buon lavoro!

### 5/5 — Get this app

*2025-02-14, version 2.0.1*

If, like me, you endured, rather than enjoyed, High School chemistry, you need this app. It's authoritative, concise, and incredibly beautiful. The knowledge it contains is as essential to understanding what we see around us as literacy. Worlds open.

### 1/5 — Unbrauchbar

*2024-12-27*

Leider unlesbar(minischrift weiśs in schwarz) das tue ich min nicht an

### 4/5 — Boring! Or maybe not.

*2024-10-17, version 2.0.1*

The only thing in this app is the Molecules-one star. OK I take it back. But since it was bad at first, I have to give it three stars. fine I can give it four stars. I was talking complete nonsense. Hooray, Mr. Gray.

### 5/5 — Get this app

*2024-08-16*

Even if you agree with Henry Ford that science is bunk, you need this app. It's not just informative, it's gorgeous.

### 4/5 — 支付问题

*2020-08-22*

我之前买了这个app，不小心删除了。重新下载，又让付钱，这是为什么呢？

### 5/5 — Great app for intuitive understanding

*2020-01-01, version 2.0.0*

Seeing realistic molecular motion while reading about the real world implications was much more satisfying that my high school chemistry classes.

This entertaining app is divided into chapters about common chemical classes (lipids, acids, organic) and properties (color, smell) that combine quirky dad humor with interactive molecular models, 3D images, and videos.  It’s the most effective educational app I’ve used with and I hope it’s the future of textbooks.

The intuitions built here would be a excellent catalyst in learning how atoms behave and interact in a classroom setting.

### 5/5 — Jiggly molecules

*2019-11-26, version 2.0.0*

10/10 molecule physics! This app is awesome

### 3/5 — Touch input bugs

*2019-05-24, version 2.0.0*

The latest update has caused the touch input to be off when interacting with the molecules on iPhone XS Max

Update: I saw the developer response and I have emailed them with the requested information and details and am awaiting a response or update. I have changed to 3 stars for good customer support and will update back to 5 stars when the bug is resolved.

### 5/5 — 不明收费，用优惠套餐补全两个软件，竟然比分开购买两个软件还贵！

*2018-12-06*

软件是很不错，我也很需要套餐内的三个软件。在苹果app支持网页投诉后，回复邮件给我竟然是建议让我联系应用开发者，我是从【App Store】上购买付款的啊！
我之前在手机上好像是花60元购买了【神奇的化学元素】这个软件，今天看到这个系列的软件有个优惠套餐，一共三个软件，剩下两个我没有购买，我以为优惠套餐价格会减去我之前购买其中一个软件所花费的价钱的。我就点击花110元购买了购买了。购买过的软件不会仔显示价格，但是我用电脑不登陆苹果账号，在itunes网页查到另外两个软件当天分别只卖30元跟68元，这样我为了补完剩下的两个软件，花费了一个优惠套餐的价格110元，不但没有减去我之前所花的成本，即使分别购买剩下的两个软件，加起来也不用再花110元啊？
苹果商店经营者如果实在不理解这件事情，简单的说就是【你们把两个软件提高价格后，放入一个优惠套餐，并且宣传比单独购买减少了xxxx元】。
这样很不合理吧，我要求给个合理方案，让我付出最少的金钱成本来购买套餐中的三个软件。
