Sure :)

."
Thanks, also this is great :) but now I am so curious to read your book :))))"
If your curiosity can't be contained, Piero, you can ..."
Paul, I have almost finished to read your plot to save Socrates.... And I am really enjoying it! :)

Dear E.B. and dear ALL,
today my short story is on Kindle! :)
I am quite excited because it is my first story published as ebook. Actually, my first fiction work (and the first in English), since in the past I have written only professional texts related to my work...and in my native Language.
I want to thank all the participants in this discussion, and I have included a specific dedication in the first pages of the book, with your names :)
At the moment it is published with the minimum price, but for the week end it should be for free (if I understood right as Kindle Platform works!)
Now I would REALLY appreciate if you read the story and write your honest review on Amazon. It is my first experience, and I want to see if reviews really work.
Thanks again!

PS: Since on Kindle I can still make amendments, I'd like to ask again for your precious help: will you suggest me another title, after reading it? And also tell me your opinion on the pen name. I dont want to publishwith my real name, not to mix my professional texts with fiction, which is an hobby. I have chosen one who has part of my real name in it, but I am not sure (and, moreover, it probably belongs also to existing persons...).
Well done, Pierro! Congrats on your first publication. Will be happy to read your short story and give you feedback. Ive bought it already, its only 77p you deserve some sales straight off for you effort.

Thanks :)
and, the biggest reward is to have people reading what you write.. and, if it happens that they like it and even leave a good review, it is more than welcome!
If you go to page where you enter the book information, there is a place in the right hand column where you can upload an image for the book cover. You have to upload the image and then resave the book info.

Actually, I can get it free now because I am an Amazon Prime member.
If you want to e-mail me the book cover and a description, I can add the book to Goodreads for you since I am a Goodreads librarian. I will send you a private message with my email address.

Okay, Piero... or should I say Peter?
The book has been added to Goodreads. Here is the link:

Well, Piero or Peter? this is the dilemma.. I wrote about above. It is not easy to find the right pen-name, and I kinda launched a survey among the forum members ;)

And John, we should be looking for the Cody book by Walter Reality?
Now that's cool.

Oooh, tx for pasting this here--would like something interesting to watch, need to get away from the PC for a breather!

Tx :) You know, I am a firm believer that pretty much anything can be made believable by decent writing. If it is an idea that has not been hammered to death already, I say give it a whirl. (Even if is has been done before, do it your way and write it well, I think you will find readers.)
I read The Guns of Napoleon over the weekend, and I really enjoyed it. I think Piero did a good job of explaining what could have been an awkward paradox. My only criticism is that I would have liked to see some parts of the story expanded as I explained in my review. Good job, Piero. I hope this is just the first of many time travel stories we see from you in the future.

Thanks a lot John for your words!
And... this is only my second story I have written in my life (in my 'past' life I have published only law-books :) ), but I have received so many (real) positive reviews on Amazon that I am quite surprised!
The only flaw is that I have sold only 1 copy Worldwide (and the buyer is Tej, see above :)), and had a couple of hundred free downloads :)

And, yes, I am developing a novel based on this short story :)

Well, IMO, even $0.99 is too much for a 30-page story. And you're charging $2.99.

hmm.. probably you're right :) but it was 0.99 before, and the result was the same...
but I will lower it again, just to see what happens :)
[in any case, I am enrolled in the select program, so people can borrow it for free... but I see zero borrows]



I wouldn't borrow anything that short. As a member of Prime, I can only borrow one item per month.
I also finished reading it and enjoyed it. I will write up a review shortly but its an assuring 3.5 stars from me (which will reflect as a 4 star rounding up). I like your narrative flow, progresses quickly (well for a short story that would be essential!), intriguing and gives a vivid post cold war backdrop without overreaching details. I also liked how it ended but I might need to read it again because unfortunately, I lost track of what the original history was meant to be! So I am not sure what actually changed (if any changes) happened to the timeline. I'll hold out on the review until I totally grasped the ending. But what I loved was the several wrong footing turn of events. The destination looked apparantly obvious but how it got there was surprising.
Well done Piero, that was a very confident first novelette and gets a heartfelt thumbs up from me.
NOW with that said...I have a gripe. Its not the same as Johns, in fact the part that John felt wasnt enough, was ironically perfect for me and a highlight, I'll explain why later in a spoiler bracket. First, I will like to point out a negative. Embrace yourself Piero, I am going to be pretty blunt here!
You laid out rules of time travel in the format of Asimov's Law of Robotics. However, the language of Asimov's robotic rules do not fit at all with your time travel rules. It just makes no sense with the way its worded.
Your first rule is fine...sort of, its a little superfluous for the sake of mirroring Asimov.
"When Travelling in time, one must not alter any event, or, through inaction, let an event is (be) altered"
That sounds like a good rule but I cant think of an example of how one can alter an event through inaction. Through action, yes but inaction? how?
Second law: "One must not leave - either in the past or in the future - an object of his own time, nor inform anyone that he is travelling in time, as long as it does not conflict with the First Law."
OK, the first part is a solid rule...then it gets nonsensical from "...nor inform anyone....does not conflict with the First Law"...yes its got an Asimov flavour but its nonsense...sorry Piero, I hope you got your guard up, I'm throwing a couple of body blows at you here, now here comes the right hook...duck!
The 3rd rule is real mess where it states "One must not make contact with another version of oneself, as long as it does not conflict with the first or the second law".
Again, this is nonsensical to use Asimov's wording in this context. Simply "One must not make contact with another version of oneself" is suffice and makes for a good rule.
There are 3 good rules there but they are boxed in with nonsense wordings! If there is a chance for you to review this, then its the only part I would like to suggest that you do (if you agree with my feedback that is). The rest of the novel was good.

To me, that would translate to allowing someone else to alter the timeline and not doing anything about it. This is kind of how the laws of robotics work (i.e. a robot cannot harm another human, nor can it allow a human to be harmed by doing nothing).
I also like your counter-argument regarding Victor. However, (view spoiler)

Thanks a lot for your words Tej :)))
And all critics are more than welcome!
I am really really pleased to read these reviews, for one simple reason: it is my first experience with fiction, and most of all .. in English Language! I have written in my life only law books, and in Italian.
So, I am more than happy!
Second, it is a first experiment before a more ambitious project, a real novel. So I am in time to make any needed changes. And... 'learn' the lesson for the future.
One comment on the three laws: they were born thanks to Goodreads.. John knows what I am talking about. It happened an afternoon, by chance, during a discussion in the forum. Yes, I simply wanted to 'copy' Asimov's law of robotics... so I am ready to change/amend them.
Oh.. about the change in the timeline... well, it has changed a lot, but I dont want to spoil your second reading :)))) Let me know ;)

For John and Tej... yes' you both are right, but this was a short story and I wanted to close it in 7500 words... wait for the novel to know what Victor did, why, and much more!
Coming before the end of the summer, I hope.
John wrote: "Tej wrote: "That sounds like a good rule but I cant think of an example of how one can alter an event through inaction..."

Yes but with time travel, you let everything happen 'as is' to avoid altering the timeline. With the robotic law, the robots must protect the humans including making interventions when they see a human in danger. In the time travel rule context, that intervention cannot apply, the rule is to "not act" to avoid alteration. So I still cannot see how an event can be altered through inaction?
(view spoiler)
Short stories cant deviate from the main focus too much and I think Piero achieves this by not being tempted to giving excess baggage in the narrative.

Shortly, here is the way how an event can be altered through inaction: imagine that another time traveler (Schmidt?) is going to change the past with an action - Killing someone for example... Here comes our hero, our time traveler (Victor?) can be 'inactive' and let Schmidt kill someone and change history, or can intervene and stop Schmidt, preventing him to commit any action that would cause 'alteration of an event' :)
More or less like in the law of robotics....

Ah, inaction by allowing another time traveller to alter the original event. Gotya! Yep, the first law is sound.
But the second two laws...? Go on Piero, put me in my place with those two as well ;)

'One must not leave - either in the past or in the future - an object of his own time, nor inform anyone that he is traveling in time, as long as it does not conflict with the First Law.'
hmm.. me think ... :)
Obviously you cannot leave any object of your time (or tell anyone you come from the future) not to risk to 'infect' the past with modern technology or information, right? But, following the structure and idea of the second law of robotics, if doing that can prevent major damage, it is allowed.
For example, the villain Schmidt is once again trying to change history; our hero needs then, as extrema ratio, to inform someone, and to reveal that he's coming from the future. Or, perhaps, give a modern gun to someone in the past, in order to allow him to shoot Schmidt, or.... well, I admit, no more precise examples come in my mind now... Anyhow, I will keep you posted! :))))

Law No. 3
'One must not make contact with another version of oneself, as long as it does not conflict with the First or the Second Law.'
Always following the reationale of the law of robotics, if it is absolutely needed to preserve history, I can contact my oneself in the past and inform him of something important.... Yes, I know, I dont have an example here, and the reasoning is not perfect. I will try to improve the laws, or to eliminate them for my next story! ;)
Piero, those laws still fall apart when you try to connect the 3 of them together. The Robotic laws are different, they have a correlation to each other. Yours dont, they do not connect to each other.
BUT I understand what you are trying to convey and I like it. Its just the wordings of the laws you state, do not reflect the laws in your mind because your are trying too hard to use the wordings of the robotic laws which are not really compatible. Ignoring Asimov's language, I'll restate what I think your laws are in two separate stages. The first stage will be to state the laws of a time traveller visiting an ORIGINAL uncontaminated and un-threatened timeline, assuming the laws are to protect the original timeline which I think is the main purpose of your laws just as the Robotic Laws main purpose is to protect humans:
1st law: When time travelling, one cannot alter an event.
2nd Law: One cannot leave any objects of his/her time behind.
3rd Law: One must not make contact with oneself.
Also you have a 4th law embedded unnecessarily in your 2nd law:
4th Law: One must not inform anyone in the destination era, that he/she is travelling in time.
OK that is the first stage of laws that I am sure you will agree reflects your laws but under the condition of travelling to an original uncontaminated and un-threatened timeline.
Now here is the funkiness of your train of thought which as I said, I like. What I think you are trying to do is incorporate a protection against other time travel entities that have already or are threatening to contaminate the original timeline. The problem is, you can have a time traveller who is travelling in time simply to observe. If he/she witnesses an attempted or already altered event, your laws are demanding that the time traveller do something to either prevent or restore the event to its original state. But that time traveller may not be trained to take such actions. Therefore your protection upgraded laws really should be served as a guideline for time travel policing.
But anyway, lets modify the rules to reflect this extra protection:
1st law: When time travelling, one cannot allow an event to be altered.
2nd Law: One cannot leave any objects of his/her time behind unless it is required to prevent alteration by another time travel entity or to restore an already altered timeline to as close to its original state as possible.
3rd Law: One must not make contact with oneself unless it is required to restore an already altered timeline to as close to its original state as possible.
4th Law: One must not inform anyone of the destination era, that he/she is travelling in time unless it is required to restore an already altered timeline to as close to its original state as possible.
So those four laws pretty much covers everything that I think you are trying to convey. SO I'll try correlate this as best I can to the robotic laws. We need to directly match the main players. Human = Original Timeline. Robot = Time Traveller.
Lets first state Asimov's classic Laws of Robotics:
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
Now lets traverse that with your time travel rules replacing robot and human with time traveller and Original Timeline
1. A TIme traveller may not alter the timeline or, through inaction, allow the timeline to be altered.
2. A time traveller must not leave an object behind unless it would conflict with the First Law.
3. A time traveller must not be in contact with his younger/older counterpart as long as it does not conflict with the First law.
So if you insist on using the Robotic laws structure, this would be a more logical wording.
However, as I said, its more of a policing set of rules. If I was to lay out rules for the time traveller observer who has no training or skill to police attempted or restoring altered events, it would be the previous set of laws I mentioned.
This was fun...but I am really sleepy now :)

And trying to "fix" something that was altered will more than likely just alter it more.
I think Murphy's Law trumps any other Laws.

If you push something hard enough, it will fall over.
And I hope Tej got some sleep with sweet dreams.

Yes, Tej, it was fun :)
And probably n my next stories I will not state any law... it is enough to let the reader guess them ;)

And trying to "fix" something that was altered will more than likely just alter it more.
I think Murp..."
This is absolutely true! :))))
I remember a very funny episode of the Simpson on this subject...

I can't say that it reminded me of Millenium at all but I liked E.B.'s comparison to Terminator, I see similarities in the potential paradox but it's funny, I don't consider either a loop, exactly... recursive, certainly but more of an expanding spiral than a circle. I mean, I think there was a 'prime' time line with no John Connor and I like the idea here, that there might have been past versions of Victor (or other agents) with each trip to the past creating bigger changes to the present, each adding to the last.
There were some episodes of Star Trek The Next Generation this reminds me of. One episode was Cause and Effect. It was very much a loop but they were able to leave clues for the next loop that were eventually enough to get themselves unstuck. Another was a two parter: Time's Arrow where they find Data's head but much older. We then see over the course of the two episodes why his head was left in the past.
I also have to say I have no problems with your first two laws of time travel but agree the third could be reworded. You've already established an homage to Asimov with the first two and could even be a little ominous with a much more concise third rule: Never interact with an alternate version of oneself.
It would also be clearer and offer nice foreshadowing, if we see these rules put in action at some point to justify thier presence in the story at all, unless you want to make Tej's interpretation of the humor at the end seem more intentional, which would also be a great way to go!


Wow.. This is very interesting!
And thank you for the good critics on my writing :) The best reward for a writer :)

I can see you guys are serious about time-travel! I have no specific answers to his questions, because I believe that his actual story is primal, and the “scientific explanations” are secondary. Besides, he’s gotten plenty of excellent possible answers from this group.
My personal bias is for hard science fiction rather than soft fantasy, but for me the actual story-telling is what keeps me reading: the science has to be in service of the story. As such, I think different stories require different time-travel rules. (I know I’m going to catch hell for this POV.)
In my favorite two science fiction time-travel novels the actual science is incidental. One is an oldie. In FARNHAM’S FREEHOLD what most interests me are the interactions among the characters, and the actual skewed future presented. Farnham met himself at one point. “Atomic-bomb-go-boom” threw his family into the future. All I can remember about getting back was something about an Experimental Chamber, that nobody even knew if it would work, as I recall. My other fave time-travel novel is by a newbie, Sadie Forsythe: in THE WEEPING EMPRESS there are no time-travel explanations whatsoever, she just dumps her heroine into an alternate past . . . deal with it girl. Since she has to fight to survive from HOUR ONE that is what makes the story work. I also perversely enjoyed the way her heroine rose to command her new world absolutely, without using any future knowledge or future science to do so; and the way she worried more about how her daughter in the future would survive without her than about her own survival in her new twisted past.
The science in time-travel science fiction must present a plausible explanation where needed to allow the reader to suspend disbelief and enjoy the story.
One of my favorite science fiction resources for writers is the obsolete but still relevant THE SCIENCE IN SCIENCE FICTION by Peter Nicholls ©1983. It is a good jumping-off point for further research; although the data-points must be double-checked, as it confidently states that Earth’s moon has 1/5th-G gravity. [If anyone can suggest a circa 2013 replacement for this all-in-one-place sci-fi resource, I would Greatly Appreciate it!!] But I love the way this book presents alternate ways of explaining, well, just about anything, including time-travel.
My take is that as long as the reader is enjoying the story, the writer can get away with all sorts of scientific discombobulations.
I once wrote a literary exercise that turned into a time-travel short story. I had bought a book of clichés, which writers should avoid, but the moment I saw the long list of wonderful clichés on “Time,” I rebelliously decided to write a time-travel short story using EVERY LAST ONE OF THE TIME CLICHES. Because I was playing for laughs, the “science” for my time-travel was intentionally as absurdly ridiculous as I could conceive.
Later, I wrote a hard science fiction time-travel novel (as HARD as I am able to make it, anyway); what worked for me here was a future branch of science called Time Renormalization (as crazy as Quantum Theory, involving an analysis of vectors propagating bidirectionally in time: “An event without a future vector or a past vector cannot actualize.”), to avoid logic paradoxes involving time-travel, and explain how the Future-Jack was able to meet the Past-Jack but would be unable to kill him. And by the way, I’m sorry, but if you think Quantum Theory is sane, you don’t understand it.
Anyway that’s my two cents on the science of time-travel science fiction, and Piero’s questions: it doesn’t matter how you get to plausible as long as the reader is having fun. Cheers! @hg47

And, I am curious about your two sci-fi works, can you tell us where to find them? :)

And, I am curious about your two sci-fi works, can you tell us where to find them? :)"
Hey, Piero! Only one of my sci-fi novels is available, the other isn't worth reading. You should be able to find my DAUGHTER MOON by @hg47 at Smashwords or Amazon; it's in eBook format now; Print version in a few weeks.
How about you, Piero? Have you written some science fiction that I can read?
In the Nineties, one of my novels was picked up by Longstreet Press, but it went out of print, and Longstreet went out of business. Now, I'm trying the self-publishing route. Last year I had several eBooks out, but nobody much liked them, except for DAUGHTER MOON. Readers seem to like that one. Cheers! @hg47

Just wondering.
Good luck either way."
Hey, Howard! Thanks for asking. DAUGHTER MOON is hard science fiction, but time travel is integral to the story. Girls on the moon, in a high-tech future where the male sex has been eliminated--whoops, here comes a male time traveler. So, which of your books should I look at? Notice you don't review books here on GoodReads. Cheers! @hg47

Hey Howard, I am going to look for your Epic Fables as well..
Nice to see you authors reading each others work. I imagine your feedback to each other would give a nice writers perspective to contrast with readers.
