The actual book starts off much more smoothly and introduces concepts step by step
(see &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;cnd.mcgill.ca&amp;#x2F;~ivan&amp;#x2F;miniref&amp;#x2F;noBSguide2LA_preview.pdf&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;cnd.mcgill.ca&amp;#x2F;~ivan&amp;#x2F;miniref&amp;#x2F;noBSguide2LA_preview.pdf&lt;/a&gt; for a preview).&lt;p&gt;The &amp;quot;onboarding&amp;quot; in the math&amp;#x2F;phys book (&lt;i&gt;No bullshit guide to math and physics&lt;/i&gt;) is even smoother. About 1&amp;#x2F;3 of the text is a review of high school math topics, which helps to establish a solid foundation understanding mechanics and calculus. (see &lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;minireference.com&amp;#x2F;static&amp;#x2F;excerpts&amp;#x2F;noBSguide_v5_preview.pdf&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;minireference.com&amp;#x2F;static&amp;#x2F;excerpts&amp;#x2F;noBSguide_v5_previe...&lt;/a&gt; for a PDF preview.)&lt;p&gt;You are absolutely right though, many of the readers who have written to me over the years are adults who used the book to review what they learned at university. The compactness works well for that.</text><parent_chain><item><author>thesimon</author><text>It is probably a great idea, but looking at the sample it looks like just another textbook that is hard and complex:&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;cl.ly&amp;#x2F;image&amp;#x2F;150V0z3T2b0g&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;cl.ly&amp;#x2F;image&amp;#x2F;150V0z3T2b0g&lt;/a&gt;&lt;p&gt;In contrast to that, I found &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;openstaxcollege.org&amp;#x2F;books&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;openstaxcollege.org&amp;#x2F;books&lt;/a&gt; a really awesome resource for learning physics (on an easy level)&lt;p&gt;Edit: Cutting out all the &amp;quot;bullshit&amp;quot; seems to make it hard for a &amp;quot;busy adult&amp;quot; to easily learn the concept, but it actually seems like a good resource to improve your knowledge which you simply forgot.</text></item></parent_chain></comment><story><title>No bullshit guide to math and physics</title><url>http://nobsgui.de/to/MATHandPHYSICS/</url></story>
<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>whitewhim</author><text>Looking at the sample, I agree with you. Condensed ≠ easy to understand. Honestly, a lot of the graduate texts I deal with look easier to understand. In my opinion, every single concept should be introduced with physical analogies if one wishes a reader with no maturity in the subject to actually understand. Then again if the author is going for &amp;quot;no-bullshit&amp;quot; this could serve as a good reference for someone who just needs a quick easy to understand reference.</text><parent_chain><item><author>thesimon</author><text>It is probably a great idea, but looking at the sample it looks like just another textbook that is hard and complex:&lt;p&gt;&lt;a href=&quot;http:&amp;#x2F;&amp;#x2F;cl.ly&amp;#x2F;image&amp;#x2F;150V0z3T2b0g&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;cl.ly&amp;#x2F;image&amp;#x2F;150V0z3T2b0g&lt;/a&gt;&lt;p&gt;In contrast to that, I found &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;openstaxcollege.org&amp;#x2F;books&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;openstaxcollege.org&amp;#x2F;books&lt;/a&gt; a really awesome resource for learning physics (on an easy level)&lt;p&gt;Edit: Cutting out all the &amp;quot;bullshit&amp;quot; seems to make it hard for a &amp;quot;busy adult&amp;quot; to easily learn the concept, but it actually seems like a good resource to improve your knowledge which you simply forgot.</text></item></parent_chain></comment><story><title>No bullshit guide to math and physics</title><url>http://nobsgui.de/to/MATHandPHYSICS/</url></story>
