POINTSIN is a civil engineering and survey tool that reads point data (ID, North, East, Elevation, Description) from a file and inserts an attributed Land Desktop(Softdesk/DCA)-style POINT block and a 3d point in AutoCAD for every point in the file. It also has a command to create a single point.
You can change the POINT block if you prefer. The order and graphical arrangement of the attributes doesn't matter. The default POINT block attributes are one unit high. POINTSIN scales the POINT block to the dimension text height (dimscale * dimtxt), so the default POINT block will look as big as the current dimension text height.
You can delete or comment out the lines that insert a 3d point or the POINT block. You can also comment out the lines that create and set layers.
Download POINTSIN.LSP (save it to your computer) by following the link on this page. Also download POINT.DWG (save it to your computer) by following the link on this page or make your own POINT block. If you don't have a points data file to import, you may also want to download the sample POINTS.TXT file.
At minimum, all POINTSIN.LSP needs to work is the POINT block and points data file. Simply drag POINT.DWG from Windows Explorer into your drawing, then load and run POINTSIN.LSP by dragging it into your drawing, typing POINTSIN, and following the prompts to select the data file. That's all there is to it.
It is a very simple matter to change layer behavior. Please open POINTSIN.LSP in NOTEPAD.EXE for guidance.
It is a very simple matter to change whether POINTSIN.LSP inserts 3dpoints, point blocks, or both. Please open POINTSIN.LSP in NOTEPAD.EXE for guidance.
It is a very simple matter to add more file formats. If you need an unsupported file format and you aren't comfortable adding it yourself after reviewing the source code, please contact me.
POINTSIN.LSP neither creates additional files nor writes to the Windows registry.
: Detailed breakdowns of angular momentum, spin, and the explicit hydrogen atom solutions.
A learner struggling with the boundary conditions could re-read the section in Chapter 3 where the authors solve a similar one-dimensional "particle-in-a-box" example in detail. By mirroring the logic but applying it to their specific well width, they can derive the correct result. The "aha" moment comes from mapping the example's structure to the new problem's parameters, not from peeking at a final answer.
If you hit a brick wall, look at the solutions manual only until you find the next logical step or integration trick. Close the manual immediately.
The solutions manual for this book is a valuable resource for students and instructors, providing step-by-step solutions to the exercises and problems presented in the textbook. : Detailed breakdowns of angular momentum, spin, and

The solutions manual for the textbook provides detailed solutions to the exercises and problems presented in the book. The manual is a valuable resource for students who want to deepen their understanding of quantum mechanics and for researchers who need to verify their calculations.
| Chapter | Classic Problem | Why the Solution is Non-Trivial | |---------|----------------|--------------------------------| | 3 | 3.15 – Harmonic oscillator via ladder operators | Requires algebraic recursion and normalization constants. | | 5 | 5.9 – Angular momentum addition | Clebsch-Gordan coefficients and CG table usage. | | 7 | 7.4 – Stark effect for hydrogen | Perturbation theory with degenerate states and matrix diagonalization. | | 9 | 9.2 – WKB connection formulas | Careful handling of Airy functions and turning points. | | 12 | 12.6 – Born approximation for Yukawa potential | Fourier transform of exponential potential. | | 14 | 14.3 – Dirac equation free particle | Gamma matrices, spinors, and positive/negative energy solutions. | The "aha" moment comes from mapping the example's
While official digital versions of the solutions manual may not always be readily available or may require purchase, there are instances where PDFs of such materials are shared online. However, students should be cautious and ensure that any digital resources they use are obtained through legitimate channels, respecting the intellectual property rights of the authors and publishers.

Some companion guides exist for similar texts, but Bransden & Joachain lacks an official student version. However, check publishers like CRC Press or Springer for problem-solving books in quantum mechanics (e.g., Problems in Quantum Mechanics by Flügge or ter Haar).
